What this seal does

The SKF 19264 is a rotary shaft seal built to CRW1 design with a single nitrile rubber lip and a carbon steel spring. It fits a 1.938 in shaft inside a 2.75 in bore and is rated for fluids such as mineral oils, gasoline, diesel, greases, hot water and light heating oil at pressures up to 10 psi.

Check before ordering

Verify the shaft diameter is exactly 1.938 in and the housing bore is 2.75 in with the correct chamfer for press-fit installation. Confirm the application stays within 3,000 RPM and 7.77 mps surface speed, and that the fluid type matches the compatible list. The overall width is .313 in, so ensure the gland depth accepts this dimension.

Behaviour under sustained load

At continuous speeds up to 3,000 RPM the carbon steel spring maintains lip contact while the nitrile rubber resists hardening from mineral oils, gasoline, diesel and greases. The acrylic case coating protects against corrosion during long runs, and the single-lip CRW1 design limits heat buildup at the 7.77 mps surface speed rating.

Questions about this item

Does the SKF 19264 shaft seal come with any installation tools or lubricant, or must those be purchased separately?

The box contains only the CRW1 rotary shaft seal itself; no installation tools, lubricant, or additional hardware are included.

Should I choose the 1.938 in inside diameter version or is another size available for this model?

Model 19264 is manufactured with a single inside diameter of 1.938 in, an outside diameter of 2.75 in and a width of .313 in; no alternative dimensions exist for this part number.

What does the 3,000 RPM maximum rotational speed mean for an engine running at highway speeds?

The seal is rated for up to 3,000 RPM and a surface speed of 7.77 mps, so it will handle typical crankshaft or transmission input speeds within those limits.
