SKF 12364 Rotary Shaft Seal

The SKF 12364 is a CRWA1-design rotary shaft seal built for automotive and RV drivetrain applications. It fits shafts with a 1.25 in inside diameter and seats into a 1.752 in bore, using twin nitrile rubber lips and a carbon steel spring to retain lubricants and exclude contaminants.

Build integration and clearance

The seal installs directly into the housing bore without additional machining, relying on its 0.25 in overall width and acrylic-coated case for a secure press fit. Its lip geometry handles surface speeds up to 6 mps and rotational speeds up to 3, 600 RPM, freeing the builder from specifying separate wear sleeves or external dust covers.

Ideal use cases and limits

This seal suits service on differential pinions, transmission output shafts or pump drives that run in mineral oils, diesel, gasoline, greases, hot water or light heating oil at pressures no higher than 10 psi. Buyers needing higher pressure ratings, larger shaft diameters or fluorocarbon lip material for aggressive chemicals should look at alternative seal families.

Questions about this item

Will the 10 psi pressure limit be reached first under sustained use?

The seal is rated for a maximum of 10 psi; exceeding this pressure will cause failure before other limits are reached.

How much heat is generated when the seal runs continuously at 3,600 RPM?

At 3,600 RPM the nitrile rubber lip operates within its designed temperature range; no additional cooling is required.

What shaft diameter must the existing equipment have for this seal to fit?

The seal requires a shaft with a 1.25 in inside diameter and a housing bore of 1.752 in.
