Technology Overview

Turn to Timken No one knows bearings and how to protect them, better than Timken. Our complete line of high-performance oil seals and bearing isolators are specifically engineered for long life and high performance in the toughest applications. Turn to us for longer bearing life, increased productivity and reduced maintenance costs.
Oil Seals Creating the most advanced seals for heavy industrial markets requires quality materials. Timken industrial seals are manufactured using special elastomers that are engineered for high-abrasion resistance, low wear and outstanding temperature and chemical resistance. In addition, we have materials and designs suited for a wide range of applications and our color-coded seals help you identify the seal to ensure you are using the right seal for the right application. Available in a variety of sizes, our seals include:

Timken N Black Peak Temp. = 250°F (121°C)

Timken ES Blue Peak Temp. = 350°F (177°C)

Timken V Green Peak Temp. = 450°F (232°C)

Technology As a technology leader in friction management solutions, we invest in our own research and development and partner with trusted suppliers to develop the highest quality materials for all of our products. Our new line of seals is no exception.

Product quality ­ and resulting uptime and performance ­ depend heavily on material selection. Remember, all radial lip seals are contact seals. The elastomer of the seal contacts the rotating element of the equipment and, over time, all elastomers will wear away. The difference in how competing seals perform is in the materials. Our oil seals are made with elastomers that are designed to minimize wear, improve seal life and increase uptime.

Taber Abrasion Resistance The elastomers used to make Timken oils seals were developed with a special emphasis on abrasion resistance. In testing, our seals perform up to 90 percent better than seals made from traditional materials.

Bearing Isolators Timken bearing isolators are an optimum choice when you require an extra layer of protection from contaminants in tough applications, such as pumps, motors, gearboxes and other rotating heavy equipment. Our metallic bearing isolators feature a cam lock design and an engineered unitizing ring, providing enhanced protection in a broad range of environments. Made from PTFE material, our non-metallic bearing isolators also offer superior protection.

Engineering Data

General Specifications Timken industrial seals offer a leading combination of quality, technology and high performance. However, there are additional considerations ­ such as shaft finish, temperatures and other operating factors ­ that can impact the level of performance achieved. We recommend the following practices to ensure that you are maximizing the efficiency and the life of your bearings and machinery. For specific application assistance, contact your Timken sales representative.
Shaft Finish The amount of contact between the shaft surface and the sealing element, and the condition of the shaft surface, has a significant impact on how well seals perform. Shafts containing "threads" or other texture are simply not able to be sealed effectively. Replacement oil seals always require new sealing surfaces.
Unless otherwise indicated, it is recommended that shaft finishes have a hardness of 30 to 40 Rockwell C. A minimum of 45 Rockwell C can provide extra protection from damage during handling or installation. See Table 1.

Table 1: Shaft Requirements

For best results and finishes we recommend using the plunge grind method. We recommend 10-20 µ in. Ra (0.25-0.50 µm) with no machine lead, scratches, dents, corrosion, pits or other surface defects.
Shaft Lead Spiral grooves, or lead, may be generated on a shaft surface by the relative axial movement of the finishing tool (lathe, belt, grinding wheel, etc.) during the finishing operation. Lead on a shaft can negatively affect a radial lip seal, allowing severe leakage and leading to sealing failure.
Detecting Lead It is nearly impossible to manufacture lead-free surfaces, but the thread method allows lead to be detected and quantified. To do so, use the following procedure:
1. Mount shaft or sleeve in holding chuck.
2. Use 5 to 10 cps viscosity silicone oil to lightly coat the shaft or sleeve.
3. Because the most accurate results are achieved when the setup is level, check to ensure that the shaft or sleeve is level with the assembly.
4. Find a length of 100 percent extra strong quilting thread (dia. of 0.009 in. or 0.23 mm) or unwaxed dental floss for next step.
5. Use the thread to drape over the surface of the shaft and attach one ounce (28 g) weight at a distance below the shaft that will create a string-to-shaft contact arc of 220 degrees to 240 degrees.

6. Adjust machine's rotational speed to 60 RPM.
7. Measure the axial movement of the thread while the shaft or sleeve rotates for a period of 30 seconds.
8. Look for movement at both edges of the shaft by placing the thread there as well.
9. Reverse the direction of the shaft or sleeve rotation and repeat the test.
10. Refer to Table 2 to determine results.

Comparing Shaft Lead ­ Lead Angle The lead of a shaft is compared with other shafts of differing diameters by calculating the lead angle. This is found by dividing the string advance by the product of the shaft circumference (both in inches), and the number of revolutions required to advance the string the measured amount.

LEAD ANGLE =

String Advance

(Shaft circumference) x (number of turns)

For example, a string will advance 0.300 in. in 30 seconds on a 4.000 in. shaft rotating at 60 RPM. The lead angle equals 0.0456 degrees = 0 degrees 2 minutes 44 seconds. A 2 in. shaft with the same advance (0.300 in. in 30 seconds at 60 RPM) has a lead angle of 0.0912 degrees = 0 degrees 5 minutes 28.3 seconds.

For best seal performance, industry standards recommend that the lead angle of a shaft be 0 degrees +/- 0.05 degrees (+/- 0 degrees +/- 3 minutes ).

Shaft-to-Bore Misalignment Shaft-to-bore misalignment is the distance by which a shaft is off center relative to its bore. To measure this, calculate the distance between the shaft center line and the bore centerline, as shown in Figure 5.

Pressure Data Table 3 shows the maximum operating pressure suitable for standard oil seals and Table 4 shows maximum pressure limits for a variety of sealing options. If an application generates higher surge pressures than what are listed, full details should be submitted for design consideration and engineering recommendations. Custom and high-pressure seals can be developed, although features such as ability to take greater eccentricities may be sacrificed to gain pressure capabilities. If possible, machine designs should include vents to allow the seal to operate more efficiently.

Dynamic Runout Dynamic runout is the amount by which a shaft, at the sealing surface, does not rotate around the true center. You can measure dynamic runout by holding a dial indicator against the shaft surface while it is slowly rotated. The resulting measurement is called a total indicator reading, or TIR. See Figure 6.

Bore depth standard tolerance is +/- 0.016 in. (0.4 mm).

Surface Speed Shaft finish, misalignment and runout, lubrication, pressure and seal design are all factors in determining safe operating speeds and become more important the more the shaft speed increases. To determine the appropriate surface speed for your application(s), use the formulas below or see Appendix F for the surface speed chart. Because surface speed limits vary with seal design, also refer to the product listings for limits on specific Timken industrial seals.
Surface Speed (f/m) = Shaft Dia. (in.) x RPM x 0.262 Surface Speed (f/m) = Shaft Dia. (mm) x RPM x 0.0103 Surface Speed (m/s) = Shaft Dia. (in.) x RPM x 0.0013299 Surface Speed (m/s) = Shaft Dia. (m/m) x RPM x 0.0000524

· Typically, the shaft has a wear groove created from previous seals. Make sure the new sealing lip does not seal in the same location.
· When drive features such as keyways or splines are present, they must be covered using an installation tool similar to the one shown in Figure 10 below, and using "Installation Method D" shown in Figure 10 on the next page. If the use of a tool is prohibited by the size of the shaft, use one of the following options:
· Polyethylene tape · Brass shim stock with smooth edges · Wooden plug with smooth edges

Figure 10: Installation Methods

Solid Seal Installation Install the seal(s) using one of the proper installation methods shown in Figure 10. When using installation tooling, the diameter, or contact area, should not be more than 0.010 in. (0.254 mm) smaller than the bore diameter. If the use of an installation tool is prohibited by the size of the seal, then:

· Rest a block of wood (piece of 2 in. x 4 in. or similar) on the seal and use a mallet to drive the seal into position. Do not hit the seal directly with the mallet, as it may cause damage.

· When using this method,

Seals Installation Instructions

· Continue by rotating the wooden block to the appropriate positions (3 and 4, 5 and 6, 7 and 8), hitting the center of the block with the mallet each time.
· Repeat the pattern until the seal is properly seated in the housing bore. The seal is fully seated when the difference between the seal surface and the housing surface is equal to or less than 0.010 in. (0.254 mm).

IMPORTANT NOTE The 0.015 in. protrusion will be built into the width of the seal. The depth of the bore housing should be machined to the seal width specified on the package.

Split Seal Installation Ambient pressure/non-flooded applications only
· Apply a thin coat of lubricant to the seal lip and shaft.
· Split the seal along the axis of rotation (shown in Figure 12) and place the seal around the shaft.

Figure 13: Split Seal Installed
Inspection After installation, inspect the sealing areas for leaks, paying special attention to the area around the sealing lip and the OD. Make sure that the sealing lip is not in the groove worn into the shaft from the previous seal.

Figure 12: Split Seal Separation
· Beginning with the split ends, insert the seal into the top of the housing bore. Make sure the split ends of the seal are touching.
· Working downwards on both sides, continue inserting the seal into the housing bore, finishing at the bottom.
· Once the seal is properly seated in the housing bore, it should protrude from the housing surface by 0.015 in. (0.381 mm), as shown in Figure 13. The 0.015 in. protrusion is built into the width of the seal. The depth of the bore housing should be machined to the seal width specified on the packaging.

Timken Bearing Isolators Installation Instructions

Installation Instructions Isolators

Equipment Preparation Before installing an isolator, all equipment should be inspected. First, disconnect all power to the machinery and follow standard safety procedures to avoid personal injury or equipment damage during installation.
Second, inspect the shaft and bore surfaces. The shaft finish should be better than 64 µin (1.63 µm) with minimal lead, but a polished surface is not required. The bore surface should be 64 µin (1.63 µm). Both the shaft and bore should have a chamfer or other edge relief to prevent the o-ring from shearing.
Third, check the shaft and bore for damage or imperfections. They should both be clear of burrs, nicks, indentations and any other defects. Clean all foreign debris from the area. Note that, in many cases, the previous seal may have worn a groove into the shaft. Make sure that the rotor o-ring of the new seal does not ride in this area.
Finally, if drive features such as keyways or splines are present on the shaft, they must be covered during installation. To do so, use an installation tool, polyethylene tape, brass shim stock with smooth edges or a wooden plug with smooth edges.
Seal Preparation
IMPORTANT NOTE Timken metallic and non-metallic bearing isolators are unitized, and any attempts to take them apart will not only cause seal damage, but will void the warranty on the product.

If your isolator has a drain port, rotate it to the 6 o'clock position. For isolators with a mark on the OD of the stator, rotate it to the 12 o'clock position to ensure appropriate positioning of the drain port. Some nonmetallic bearing isolators may be installed in any direction, and there is no need to position the seal. See Figure 15 for clarification, or contact your Timken sales representative if you require additional information.
Drain at 6:00 position, Mark at 12:00 position.
Figure 15: Drain Port Positioning
Using your hands only (no installation tool required), push the isolator gently into the bore. If required, gently tap the isolator using a soft-faced mallet. While flanged isolators are fully seated when the flange is flush against the housing, flangeless isolators can be installed at the bottom of the housing and are fully seated when they are flush with the bore face. See Figure 16 for clarification.

Before installation, inspect the o-ring's OD and ID, making sure they are free of any defects. Use the lubricant included with your isolator to lightly grease all the o-rings. Installation Using your hands only (no installation tool required) push the isolator evenly onto the shaft as shown in Figure 14.
Figure 14: Seal Installation on Shaft

Figure 16: Flanged Seal Flush with Housing Face
Post-Installation Inspection After installation, inspect the sealing area for damage. Gently spin the shaft to make sure the rotor is working properly.
IMPORTANT NOTE Do not flood the isolator or block the expulsion ports, as these actions can cause seal damage and failure.
Removal To remove an old isolator from your equipment, start from the back side of the seal and perform installation instructions in reverse. If access to the back side of the isolator is difficult, pry it from the housing a little at a time. Be careful not to damage the shaft or housing bore during seal removal.

Front Lip Angle Contact Point

Back of the Seal Seal OD - Heel

Back Lip Angle Hinge

Assembled Seal:

Seal made up of a group of parts, including sealing surface(s), provisions for initial loading and a secondary sealing mechanism to accommodate radial movement required for installation and operation.

Axial

Gap between element heel and seal lip.

Clearance:

Back Lip Angle:

Angle seen from the back of the seal coinciding with the seal interface.

Bearing Isolator:

Product using labyrinth sealing methods and other techniques to provide highperformance sealing technology for demanding applications in operating environments with high levels of contamination.

Bonded Seal:

Assembly in which the insert and/or spring is bonded to the elastomer sealing element.

Contact Point:

Interface where sealing element reacts with the shaft or bore housing.

Contact Line Axial distance from seal face to

Height:

contact point.

Contact Width:

Amount of area reacting dynamically in the axial direction.

Dynamic Runout:

Amount by which a shaft, at the sealing surface, does not rotate around the true center. Measured by holding a dial indicator against the shaft surface while it is slowly rotated. The resulting measurement is called a total indicator reading, or TIR.

Elastomer:

Synthetic and natural materials that are able to be vulcanized and can be elongated at least twice their original length at room temperature, but are able to return to their approximate "normal" length when released. Common material used in the manufacture of seals.

End Play:

Measurement of axial movement allowed, in reference to the shaft on which the seal lip comes into contact.

Face Lip Angle:

Angle seen from the face of the seal coinciding with the seal interface.

Fluid Side:

1.) Refers to face of the seal when goal is to retain lubricant. 2.) Refers to the back of the seal when goal is to exclude contamination.

Garter Spring:

Helically coiled wire in the form of a ring that helps maintain a radial sealing force between the radial seal lip element and a shaft or bore. A close wound spring is used for tension and an open wound is used for compression.

Heel:

Part of lip seal case located tangent to the back of the seal.

Hinge:

Point at which the seal lip pivots around the seal assembly.

Housing Bore:

Cylindrical surface that mates with the OD of a standard lip seal's outer case or an external lip seal's contact lip.

Inclusion:

Retaining lubricant by facing the seal in toward the lubricant.

26

Glossary

Glossary

Inner Case:

Rigid, cup-shaped component within a seal assembly that is used as a reinforcing member, shield, spring retainer and/or lip clamping device.

Labyrinth Seal:

Sealing product that uses an intricate pathway to exclude debris and retain lubrication.

Lip

Innermost diameter of the seal lip,

Diameter: measured with the spring installed.

Lip Load:

Radial force exerted by the seal lip geometry and spring loading. Expressed as force-per-unit of shaft circumference.

Lip Seal:

Elastomeric element that prevents leakage in dynamic and static applications through means of geometry and loading.

Lubricant Inadequate lubrication at the seal Starvation: interface which causes premature
wear of seals.

Offset:

Radial distance between the centerlines of the seal bore and the shaft rotation.

Outer Case: Rigid structure of lip-seal assembly that houses all components of the seal assembly.

Plunge Ground Finish:

Surface texture of a shaft or wear sleeve produced by using a grinding wheel perpendicular to the rotating shaft, without axial motion.

Primary Lip:

Elastomeric sealing element that rides against the rotating surface facing 1.) inward toward the lubricant for grease inclusion or 2.) outward from the lubricant for contaminant exclusion.

Radial Lip Seal:

Assembly containing an elastomeric element that prevents leakage in dynamic and static applications through means of geometry and loading.

Radial Load:

Radial force exerted by the seal lip geometry and spring loading. Expressed as a force-per-unit of shaft circumference.

Roughness: Anomalies in the surface texture of the shaft which result from the manufacturing process. [See SAE J448a (June 1963)]

Seal Case: Rigid member to which the elastomeric element is attached.

Seal Outer Diameter (OD):

External diameter of the lip seal assembly that interfaces with the housing bore diameter.

Shaft

Radial distance describing how much

Eccentricity: the geometric centerline of the shaft

is displaced from the axis of the shaft

rotation.

Shaft Lead: Helical grooves in a shaft surface that are caused by relative axial movement of the grinding wheel to shaft.

"Slip-Stick": Friction challenge caused by a sealing element that adheres to and rotates with the shaft surface until the elastic characteristics of the sealing element overcome the adhesive force, causing the seal lip to loose contact with the rotating surface long enough to cause leakage. Normally associated with non-lubricated and boundary-lubricated conditions, this cycle repeats itself again and again.

Spring Groove:

A semicircular depression in the head section of a seal that accommodates the garter spring.

Spring Retaining Lip:

Section of the primary lip that restricts axial movement of the extension spring from its proper position.

Surface Finish:

Quality, appearance and characteristics of a shaft surface due to processing such as grinding, burnishing, etc. [See SAE J488a (June 1963)]

Unidirectional/ Type of seal designed for applications

Unirotational in which the shaft rotates in only one

Seal:

direction.

Unitized Seal:

Seal assembly in which all the parts are retained in a single package.

Volume Swell:

Increase in seal size due to the absorbtion of fluid by the elastomer.

Wear Sleeve:

Replaceable metal sleeve used in assemblies to prevent grooving from contamination at the seal-shaft interface.

Weepage: Small amount of liquid leakage from a seal.

Oil Seals Appendix D ­ Failure Analysis
Identifying the Cause If just one seal in a heavy industrial application becomes damaged or fails to operate properly, it can result in extensive product and equipment damage, lengthy downtime and unexpected maintenance costs. Familiarizing yourself with damage analysis techniques can help you prevent further damage to equipment while identifying how to stop future seal and machine damage before it occurs.
The diagram below organizes common symptoms with common root causes of seal failure and is designed to help you:
· Sort possible causes of failure in a logical manner · Identify areas for data gathering · Identify, explore and display all possible causes related to the failure
to determine the root cause · Keep any collaboration on defining the root cause focused and on track

Appendix D ­ Failure Analysis Oil Seals

The following information pertains to standard installations. If you have a special installation or need advice, contact your Timken sales representative. For more information on both seal and bearing damage analysis, go to www.timken.com/industrialseals.

Carbonized Lubricant

Problem Lubricant breaks down, deposits around the main sealing interface and interferes with sealing capabilities

Potential Cause · Bearing lubricant becomes overheated

Potential Solution · Use a lubricant that can
withstand greater temperatures or decrease the temperature for current lubricant

Case Damage
Problem Seal case is damaged

Potential Cause · Improper installation
· Improper shipping

Potential Solution · Change installation
technique to prevent damage · Contact your Timken sales representative to discuss shipping alternatives and replacement

Chemical Degradation
Problem Abnormal swelling or distortion of the sealing element

Potential Cause · Sealing element material
and the material being sealed (i.e. lubricant, coolant) are chemically incompatible

Potential Solution · Upgrade to sealing
element that is compatible with the material being sealed

Delamination
Problem Seal material separates, interfering with sealing capabilities

Potential Cause Trapped air due to: · Improper installation
· Improper shipping
· Manufacturing defect

Potential Solution
· Change installation technique to prevent damage
· Contact your Timken sales representative to discuss shipping alternatives and replacement
· Contact your Timken sales representative to report manufacturing defect and arrange for replacement

Oil Seals Appendix D ­ Failure Analysis
Fractured Carrier Spring
Problem Ineffective sealing due to distortion or cracking of the carrier spring

Seal Damage Analysis ­ Appendix D Oil Seals
Excessive Seal Element Wear
Problem Wider than normal wear pattern on the surface of seal element

Potential Cause · Improper installation
· Excessive load

Potential Solution · Change installation
technique to prevent damage · Do not allow seal to carry the weight of the shaft

Excessive Leakage (Shaft/Seal Element)

Problem Leakage occurs between shaft and seal lip

Potential Cause

Potential Solution

· Incorrect seal/shaft size · Use correct seal size

· Rough surface finish · Refinish shaft surface

on shaft

to seal specifications

· Too much lubricant used · Reduce amount of

during installation

installation lubricant

· Shaft machined lead · Refinish shaft surface

(spiral grooves)

to seal specifications

· Cocked seal installation · Install seal squarely

into housing bore

· Excessive shaft

· Move seal closer to

movement (TIR)

bearing

· Previously mentioned · Reference previously

failure modes

mentioned sources/

solutions

Excessive Leakage (Bore/Seal Case)

Problem Leakage occurs between bore and seal case

Potential Cause · Incorrect seal/bore size · Rough surface finish
on bore · Use of lubricant during
installation
· Cocked seal installation

Potential Solution · Use correct seal size · Refinish bore surface
to seal specifications · Do not use lubricant
during installation (not recommended for the bore and seal case) · Install seal squarely into housing bore

Potential Cause · Excessive internal
pressure
· High misalignment/ runout
· Rough surface finish on shaft
· Insufficient lubrication · Extended seal service
· Oversized shaft

Potential Solution · Clean drain ports and
chamber vents or upgrade to seal with higher pressure capabilities · Upgrade to seal with higher misalignment/ runout capabilities · Refinish surface of shaft to seal specifications · Properly lubricate the seal · Upgrade to extended service element material or change maintenance schedule to accommodate new seal life requirements · Use proper seal size

Rolled Seal Element
Problem Seal was lip has been rolled over such that itdoes not properly engage shaft

Potential Cause · Damage during
installation

Potential Solution · Change installation tech-
nique or use proper tools to prevent seal damage
