SKF 19922 Rotary Shaft Seal

The SKF 19922 is a CRWA1 rotary shaft seal designed for retaining lubricants and excluding contaminants in rotating equipment. It suits maintenance technicians and engineers servicing industrial or automotive machinery where a 2-inch shaft diameter requires a reliable lip seal.

Nitrile Lip 10 PSI 3000 RPM Limit

The nitrile rubber lip handles fluids including mineral oils, gasoline, diesel, greases, hot water and light heating oil at pressures up to 10 psi. Rotational speed must not exceed 3,000 RPM and surface speed must stay below 7.9 mps to avoid premature lip wear or heat build-up.

Press-Fit Install Avoid Lip Damage

Installation is a straight press-fit into a 2.88-inch bore; the acrylic-coated case aids retention and corrosion resistance. The main risk is damaging the twin lips or dislodging the carbon-steel garter spring if the seal is driven in crooked or without a proper sleeve.

Questions about this item

Which shaft-seal size fits my 2-inch shaft?

The 19922 seal is built for a 2 in inside diameter, 2.88 in outside diameter and 0.375 in width.

What does the 3,000 RPM rating mean once the seal is installed?

It is the maximum rotational speed the nitrile lips can handle without overheating or losing contact pressure.

What does the 10 psi pressure limit cap in practice?

It caps the fluid pressure the CRWA1 design can seal reliably; above that the lips may lift and leak.
