SKF 34887 Rotary Shaft Seal

The SKF 34887 is a CRWA1-design rotary shaft seal built for 3.5 in inside diameter and 4.501 in outside diameter with a 0.375 in width. It uses nitrile rubber lips on a carbon-steel spring and an acrylic-coated case to seal rotating equipment in automotive and industrial maintenance.

Suits maintenance teams sealing oil, grease or fuel

This seal handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils at pressures up to 10 psi. It is not for vacuum service, high-pressure hydraulics or shafts running faster than 2,160 RPM where surface speed would exceed 10.17 mps.

Steady sealing at continuous rated speed

The twin-lip design maintains contact under sustained rotation at the rated 2,160 RPM limit without the heat build-up that short bursts can hide. Acrylic case coating resists fluid ingress while the carbon-steel spring keeps lip force consistent over long duty cycles.

Questions about this item

What shaft diameter does the 3.5 in inside diameter of the SKF 34887 seal fit?

The seal fits a 3.5 in shaft diameter, matching its stated inside diameter for proper installation.

How does the 10 psi maximum pressure rating of the SKF 34887 seal affect use with older low-pressure engine systems?

The 10 psi maximum pressure rating suits older low-pressure engine systems, keeping the NBR lips effective within their design limit.

How can I confirm the SKF 34887 seal is working correctly after fitting it?

Check for no fluid leakage at the 3.5 in shaft interface and verify the seal runs within the 2,160 RPM and 10.17 mps surface speed limits.
