SKF 13535 Rotary Shaft Seal
The SKF 13535 is a CRWA1-design rotary shaft seal built for machinery that demands reliable fluid retention. It fits shafts with a 1.375 in inside diameter and a 1.874 in outside diameter. The nitrile rubber lip material handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils. Maintenance technicians and equipment rebuilders use it to prevent leaks in rotating assemblies.
Sustained sealing at 3,480 RPM
Under continuous rotation the twin-lip design maintains contact up to a maximum surface speed of 6.38 mps. The carbon steel spring keeps lip pressure consistent while the acrylic-coated case resists corrosion from the listed fluids. Maximum pressure rating is 10 psi, so the seal is suited for low-pressure splash or gravity-fed lubrication rather than pressurised systems. Heat and friction stay controlled during extended duty cycles.
Replaces worn CRWA1 seals in inch-dimensioned
When an existing CRWA1 seal of the same 1.375 x 1.874 x .313 in dimensions shows lip wear, hardening or leakage, this unit restores the original sealing performance. The upgrade is worth it when the application runs within the 3,480 RPM and 10 psi limits and uses any of the approved fluid types. It does not suit higher-pressure pumps, larger shaft diameters or metric-dimensioned bores.

Questions about this item
How much heat does the CRWA1 seal generate when running continuously at 3,480 RPM?
The seal is rated for a maximum surface speed of 6.38 mps at 3,480 RPM with a 10 psi pressure limit, and its nitrile rubber lips are designed for mineral oils, greases and similar lubricants that dissipate frictional heat.
What shaft diameter and housing bore must I already have for the 13535 seal to fit?
The seal requires a 1.375 in shaft diameter and a 1.874 in housing bore to match its inside and outside dimensions.
Will the acrylic-coated case of this seal resist the same fluids as an older nitrile seal I might replace?
The nitrile rubber lips handle animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils, while the acrylic case coating adds external protection in those same fluid types.
