Shaft Seal 1.375 in ID

The SKF 13569 CRWA1 is a rotary shaft seal designed for 1.375 inch shaft diameters. It uses nitrile rubber lips and a carbon steel spring to retain lubricants in engine assemblies.

10 psi pressure limit

This seal handles up to 10 psi and 3,480 RPM with a surface speed of 6.38 mps. It is rated for mineral oils, gasoline, diesel, greases, hot water and light heating oil. Exceeding the pressure or speed ratings will cause premature lip wear.

CRWA1 design code

The CRWA1 code identifies a dual-lip construction with an acrylic-coated case. The secondary lip excludes dust and moisture while the primary lip seals the fluid, extending service intervals in contaminated environments.

Questions about this item

Will the 1.375 in inside diameter fit the shaft on my older engine?

The seal is designed for a 1.375 in shaft diameter; measure your shaft to confirm it matches this size before installation.

How can I verify the CRWA1 seal is seated correctly after fitting?

After installation, check that the seal sits flush in the 2 in bore, the dual nitrile lips contact the shaft evenly, and no oil weeps past the 0.313 in width during initial run-up.

Does the box include the carbon-steel garter spring or must I buy it separately?

The carbon-steel spring is already assembled inside the CRWA1 seal; the package contains the complete rotary shaft seal ready to install.
