SKF 19887 Rotary Shaft Seal
This SKF 19887 rotary shaft seal fits a 2 in inside diameter and a 2.875 in outside diameter. It is built for automotive and industrial equipment that requires a reliable lip seal. The CRWA1 design uses nitrile rubber lips and a carbon steel spring. Mechanics and maintenance teams use it to retain lubricants and exclude contaminants.
Capacity and operating limits
The seal handles fluids such as mineral oils, gasoline, diesel, greases, animal and vegetable oils, light heating oil and hot water. It operates at up to 10 psi pressure and 3,000 RPM with a maximum surface speed of 7.9 mps. The dual-lip construction and 0.313 in width provide a consistent barrier until those limits are exceeded.
Acrylic-coated case and dual-lip design
An acrylic coating on the case eases installation and helps prevent bore corrosion. Two sealing lips improve fluid retention compared with single-lip alternatives. The carbon steel spring maintains lip contact over the service life. No additional hardware or lubricants are included in the package.

Questions about this item
Will the SKF 19887 shaft seal fit a housing with a 2.875 in bore and a 2 in shaft?
Yes. The seal has an outside diameter of 2.875 in and an inside diameter of 2 in, matching those dimensions exactly.
How can I confirm the CRWA1 seal is seated correctly after installation?
Press the seal squarely until the case coating contacts the housing shoulder. The spring should remain visible behind the primary lip, and the 0.313 in overall width should be flush with the bore face.
Does the SKF 19887 come with an installation sleeve or lubricant, or must I buy them separately?
The box contains only the nitrile rotary shaft seal. An installation sleeve and compatible assembly lubricant are not included and must be purchased separately.
