SKF 24897 Shaft Seal for Rotary Applications
This SKF rotary shaft seal is designed for equipment requiring a 2.5 in inside diameter and 3.251 in outside diameter. It suits maintenance teams and original-equipment builders who need a reliable lip seal for rotating shafts in industrial or automotive drivelines.
CRW1 Design with Nitrile Lip and Acrylic-Coated Case
The seal uses a single nitrile rubber lip held by a carbon-steel garter spring inside an acrylic-coated metal case. This construction resists the listed fluids and allows straightforward press-fit installation into standard inch-dimension housings without special tooling.
10 psi Pressure Limit and 2,640 RPM Speed Rating
The seal is rated for a maximum of 10 psi differential pressure and a rotational speed of 2,640 RPM with a surface speed of 8.81 mps. It is not suitable for high-pressure hydraulic systems or shaft speeds exceeding this limit.

Questions about this item
What pressure does the CRW1 nitrile shaft seal rated at 10 psi actually hold in service?
The seal is rated for a maximum of 10 psi; exceeding this limit can cause leakage or lip damage.
What bore and shaft diameters must match the 3.251 in OD and 2.5 in ID for a correct fit?
The housing bore should be 3.251 in and the shaft 2.5 in; verify both before installation.
How do I install this 0.375 in wide rotary seal without damaging the spring or lip?
Lubricate the lip, use a sleeve over shaft keyways, and press the case evenly with a flat tool until seated.
