SKF 16085 Rotary Shaft Seal

The SKF 16085 is a rotary shaft seal designed for automotive and industrial engine applications. It fits shafts with a 1.625 in inside diameter and a 2.374 in outside diameter. The seal suits maintenance professionals and equipment operators who need reliable fluid retention on rotating assemblies.

Capacity and pressure headroom

The seal handles a maximum pressure of 10 psi and operates up to 3,240 RPM with a surface speed of 7.06 mps. Its nitrile rubber lips and carbon steel spring manage animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils. It runs out of headroom in high-pressure or extreme-speed environments beyond these limits.

CRWA1 design and inch interface

The CRWA1 design code defines a non-contact, dual-lip seal with an acrylic-coated case and an overall width of .313 in. The inch-based dimensions determine housing and shaft fitment directly. Builders using metric tooling or needing higher pressure ratings must verify compatibility before installation.

Questions about this item

Will the 1.625 in inside diameter and 2.374 in outside diameter match my existing shaft and housing?

The seal is built to a 1.625 in inside diameter and a 2.374 in outside diameter, so it fits shafts and bores machined to those exact inch dimensions.

How can I confirm the CRWA1 design and NBR lips are sealing correctly once installed?

After fitting, run the shaft up to its normal speed — up to 3,240 RPM — and check for leaks; the non-contact CRWA1 design with two nitrile lips should show no weep at pressures up to 10 psi.

Does the box include the carbon-steel garter spring and acrylic-coated case, or must I buy them separately?

The spring and coated case are integral parts of the 16085 seal; nothing extra is required for installation.
