SKF 22354 Rotary Shaft Seal

The SKF 22354 is a CRWA1-design rotary shaft seal built for 2.25 in inside diameter and 3 in outside diameter bores. It uses nitrile rubber lips with a carbon-steel spring to seal rotating shafts in automotive and industrial engine assemblies. The acrylic-coated case installs in standard inch-dimension housings without special tooling.

Suits oil-lubricated shafts up to 2,820 RPM

This seal handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils at pressures up to 10 psi and surface speeds of 8.38 mps. It is not suited for higher-pressure hydraulic systems, extreme-temperature fluids or shafts that exceed the rated speed limit. Buyers needing larger bore diameters or different lip materials should select another SKF profile.

Fits 2.25 in shaft journals

The .375 in overall width matches common engine seal grooves, leaving the shaft bore and retention hardware unchanged. The dual-lip design retains lubricant while excluding contaminants, reducing the frequency of resealing jobs. No additional spring or case components are required for installation.

Questions about this item

What shaft diameter does the 2.25 in inside diameter of the SKF 22354 seal require?

The seal fits a shaft with a 2.25 in outside diameter, so the mating shaft must measure 2.25 in.

Will the 2,820 RPM speed limit of this nitrile seal handle a legacy engine running at lower speeds?

Yes, the 2,820 RPM maximum rotational speed covers typical older engine speeds, provided the shaft surface speed stays below 8.38 mps.

How can I confirm the CRWA1 seal is seated correctly after installation?

Verify the case coating sits flush in the 3 in bore, the spring remains visible behind the dual lips, and no lip is rolled or cut.
