National Redi-Sleeves are easy to install, featuringa removable flange and an installation tool.

National Redi-Sleeves offer numerousshaft maintenance advantages:

Strong, durable stainless steel construction provides a corrosion-free sealing surface that surpasses most original shaft specifications

Ultra-thin construction (0.1" / 0.25mm wall thickness) allows original seal size to be used with minimal additional lip loading

Redi-Sleeve surface is the best-possible sealing surface, ground to a 10 - 20 microinch Ra (.25 - .50 Micrometer Ra) finish without lead

Available for shafts from .5" (12.7mm) to 8" (203mm) in diameter

National race drivers are available from stocking distributors worldwide

To select the proper size Redi-Sleeve,measure the shaft diameter where the sleevewill be positioned ahead of the wear path.Do not measure the track worn by the old seal.

Measure the shaft in three positions:12 oclock to 6 oclock, 2 oclock to 8 oclock,and 4 oclock to 10 oclock. Then average thethree readings (to compensate for possible shaftout-of-round or error in measurement).

Use this averaged measurement to selecta part number from the Size Chart provided,and order from your National Oil Seal distributor.

National Redi-Sleeves are precision stainlesssteel wear sleeves, designed to be pressed ontoa shaft to provide an excellent sealing surface.

For grooved or worn shafts, Redi-Sleeves are afast, inexpensive repair option. The Redi-Sleeveis simply pressed onto a shaft where indicationsof seal wear (such as tracks or grooves) havedeveloped; the shaft now has a smooth,ideal sealing surface.

For new shafts, Redi-Sleevesprovide superior sealing and easeof future repairs; simply pop offthe worn sleeve and press ona new one, when needed.

Use tools andcomponents only fortheir intended purposes.Follow manufacturerrepair and maintenanceprocedures. Eye protectionshould always be wornto prevent personal injury.

Remember!

Save time and costly shaft replacementsby using National Shaft Repair Kits.Our kits include the industry-tested,technician-approved seal in additionto a National Redi-Sleeve.

Depend on National Shaft Repair Kitsas a reliable, cost-effective alternativeto replacing or repairing the shaft.

Performance Features*

NATIONAL ZERO DUPLICATION PROGRAM

Each Zero Duplication seal effectively replacesseveral similar seals, providing comprehensiveapplication coverage with less inventory.

Following a thorough analysis of application needs,the National design team concluded that the vastmajority of application requirements can be met usingonly a few seal designs, if the designs incorporate themost effective performance features. The Nationaldesign team has developed a comprehensive line ofseals, in a range of common sizes, engineered to fitand perform well for virtually every industry need.

Keep lubricants and other critical fluids in, water and other contaminants out.

Spring-loaded, dual-lip sealing elementUses two sealing lips, one spring-loaded tightly againstthe shaft to retain lubricants, the other functioning as acontaminant excluder.

Double-wall caseMinimizes deformation to the case during installation and formsa secure, stable base for optimum sealing element performance.

Exclusive, Redi-Coat coatingSeals minor bore defects to help ensure a tight, leak-proof seal.

Optional fluoroelastomer sealing element(Available in selected part numbers in addition to standardnitrile seals) provides excellent high-temperature capabilities,good compatibility with a wide range of fluids, very long life.

A seal keepscontaminants out andlubricants in to protectand extend bearing life.

By consolidating your inventory into onesystematic collection of premium-quality seals,the National Oil Seals Zero Duplicationprogram provides comprehensive coveragewhile minimizing the number of replacementseals you carry in inventory.

The program is based on special selections ofNational Oil Seals, carefully designed to meetthe requirements of applications with shaftdiameters up to 12" or 300mm withzero duplication of comparable seals.

Zero Duplication is an effectiveway to do more with less so you can focus on otheraspects of your business.

NATIONAL ZERO DUPLICATION PROGRAM

By habit, a seal is often replaced by anidentical seal. Zero Duplication seals,however, offer performance equal andoften superior to the original seal. Even ifthe width, case design or sealing elementdiffer, trust a Zero Duplication sealfor optimal performance.

The Zero Duplication program offers tangibleadvantages for your customers:

Faster, more responsive customer service

Provides customers with the optimal seal for their application

Ensures you have the right seal in stock

Three Zero Duplication stocking planshave been developed to maximize coverage:

Gold (up to 6" / 160mm shaft sizes) seals used in heavy industry (pulp and paper mills, ore processing, mining operations)

Silver (up to 4" / 100mm shaft sizes) seals used in general industry (including heavy-duty, high-horsepower motors)

Bronze (up to 2.5" / 60mm shaft sizes) seals used in light-duty service (including motion control equipment, conveying operations)

There is also an option to develop acustomized Zero Duplication assortmentbased on an analysis of your present inventory.

SECTION 1-A TECHNICALOIL SEAL DESIGN AND SELECTION

TYPES OF OIL SEALS

While industry has generally preferred the double lip or single lip, spring loaded seals, a wide variety of types and stylesare produced to satisfy various application requirements.

To simplify the identification process of the oil seals a Type/Illustration column has been included in the Size, Numericaland Metric Listings of this catalog. The Type/Illustration number refers to the Oil Seal Illustration Chart. Just find thenumber on the illustration chart and the configuration of the component can be identified.

The National Oil Seal Design Description is provided to illustrate seal types and to provide operating data and limitationsfor typical applications. Factors relative to oil seal design and selection are also reviewed. After size, application and sealrequirements are determined, the proper seal can be located in the Size Section. Likewise, when the National part numberis known, the size and type can be easily located in the Numerical Section.

NATIONAL SEAL PART NUMBERING SYSTEM

The Federal-Mogul National Oil Seal Engineering Department assigns the part numbers for all general purpose andspecial purpose seals. Each type and size combination manufactured is identified by an individual part number.

Three numbering systems are generally used to identify National Oil Seals:

1. General Purpose SealsFive or six digit numbers. The first one or two digits usually signify seal type or construction.The last four digits refer to a specific assigned shaft and bore size combination but do not indicate seal size. They areassigned in consecutive order as a new shaft/bore combination is established. It may be possible to interchange sealsfor which the first one or two digits are different but for which the following digits are the same. Such an interchangedetermination should be based on whether alternative seal designs would meet the requirements of the specificapplication. Letter suffixes to part numbers within this manual usually refer to the sealing lip compound used.

2. A four digit number system is used for some seals and general purpose seal kits with primarily automotive applications.The numbers have been assigned consecutively and do not relate to seal size.

THE SEAL AND ITS FUNCTION

Oil Seal Definition

As products, oil seals may be simply described as devices that close or seal the spaces between stationary and movingcomponments in mechanical equipment . . . they prevent lubricant from escaping.

Oil seals often called grease, fluid or dirt seals are the vital components of practically every type of machine and vehicle inoperation. These seals fulfill an exacting function . . . they protect all types of precision constructed, close fitting ball, sleeveand roller bearings.

Oil Seal Function

Oil seals are used wherever shafts rotate and bearings require lubrication. In short, a seal is a barrier with three basicfunctions: 1) Retaining lubricants and liquids 2) Excluding contaminants 3) Seal or separate dissimilar fluids or gases.

Precision bearings rely on the oil seal to prevent lubricants from escaping the bearings or a specific area. Components of machines rely on the oil seal to prevent abrasives, corrosive moisture and other harmful contaminants

from entering the mechanics of the machine. Separation of fluids and gases may completely rely on the seal to prevent intermixture of two different mediums

such as lubricating oil and water.

Oil Seal In Use

In a typical application, the oil seal is installed adjacent to a bearing, sealing in or sealing out, as necessary, the variousliquids, gases or solids encountered by the particular mechanism.

Without an oil seal . . . essential lubricant can escape through thebearing and . . . harmful dirt and foreign matter can enter.

With a properly designed and fitted oil seal . . . the space betweenthe housing and shaft is securely closed or sealed. Lubricantcannot escape . . . harmful dirt and foreign matter cannot enter.

SECTION 1-B TECHNICALSealing Element CompoundsMATERIALS AND COMPOUNDS AVAILABLE FOR SEALING ELEMENTS

The environments in which a seal will operate should be determined before selecting the sealing element or lip material. Two of the mostimportant factors in material selection are Lubricant Temperature and Type.Federal-Mogul National Oil Seals offer a variety of sealing lip materials and compounds. The temperature limitations and fluid/lubricantcompatibility for most compounds are shown within the Compound Selection Chart on the following pages.National Seals are used in a wide range of applications. The seal is part of a system and is dependent on proper shaft and bore operationto function correctly.Runout, lubrication, shaft-to-bore misalignment, shaft speed, temperature, and other factors vary greatly from one application to anotherand each may affect the seals life. In a perfect system, these factors would be nominalized to achieve maximum life for all components. Toassist our customers in getting maximum performance from their sealing system, we have provided recommendations below.Operating a seal at one extreme condition will have a small effect on seal life. However, when a seal is operating at multiple extremes in thesystem, it will have a much greater impact on performance. Therefore, we ask you to use the following recommendations as a guide toachieving the maximum performance from your seal. Each material or compound has been assigned a specific letter code and is referencedin various tables and listings throughout this manual.

SECTION 1-C TECHNICALSealing System Preparation And Seal InstallationSTORAGE AND HANDLING OF OIL SEALS

IntroductionCareful storage and handling of radial lip type seals is necessary to avoid hazards prior to installation which wouldadversely affect service life.

General StorageRadial lip type seals are very robust long lived components. However, as with any precision components they should bestored with care as the service life of bearings and/or other costly machined parts may depend upon how well the sealperforms. Hazards which may be encountered include: temperature, ozone, humidity, radioactive materials, fumes, dust,grit and mechanical damage.

The storage area should be cool (60 to 90F) and with average (40 to 70%) humidity. Seals should be stored on a first in- first out basis, since even under ideal conditions, an unusually long shelf life may cause deteriora
