SKF 22353 Rotary Shaft Seal

The SKF 22353 is a CRW1-design rotary shaft seal built for 2.25 inch inside diameter and 3 inch outside diameter housings. Its single nitrile rubber lip runs on a carbon steel spring and handles animal or vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils at up to 10 psi.

Suits shafts needing a single-lip inch-dimension

Mechanics and maintenance teams sealing standard inch shafts in pumps, gearboxes or wheel ends will find the dimensions and fluid compatibility match. Builders requiring metric dimensions, higher pressure ratings, multi-lip designs or fluoroelastomer lips for aggressive chemicals should look at other seal families.

Handles 2,820 RPM and 8.38 m/s surface speed

At the rated limits the seal maintains contact on typical lubricants and cooling fluids. Beyond 10 psi or the stated speed the lip can lose sealing force, so high-pressure hydraulic circuits or very high-speed spindles exceed its comfortable range.

Questions about this item

What shaft diameter must I already have for the 2.25 in inside diameter to seal properly?

The seal fits a shaft with a 2.25 in outside diameter; the bore must measure 3 in for the outer case to seat.

Will the nitrile rubber lip withstand the diesel and gasoline exposure in my older engine?

Yes, the lip material is rated for diesel, gasoline, mineral oils, greases, animal and vegetable oils, hot water and light heating oil.

How can I confirm the seal is operating within its 2,820 RPM limit after installation?

Measure the shaft speed with a tachometer; it must remain at or below 2,820 RPM and the surface speed under 8.38 m/s.
