SKF 15204 rotary shaft seal

The SKF 15204 is a CRW1-design rotary shaft seal built for 1.5 inch inside diameter and 2.716 inch outside diameter applications. Its single nitrile rubber lip runs on a carbon-steel garter spring and is rated for 10 psi maximum pressure at speeds up to 3,360 RPM. The acrylic-coated case and 0.438 inch width suit standard inch-dimension housings in automotive and industrial equipment.

Replaces worn inch-size seals in oil

This unit replaces a leaking or hardened seal of the same 1.5 by 2.716 by 0.438 inch envelope when the lip no longer holds 10 psi or the spring has lost tension. The jump is worth it when the shaft surface speed approaches 6.74 mps and the original lip material has degraded from heat, fuel exposure or abrasive contaminants.

Fits standard inch bores with acrylic case coating

The seal presses into a 2.716 inch bore and seals against a 1.5 inch shaft running in animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil or mineral oils. The carbon-steel spring maintains lip contact through thermal cycling, freeing the builder from frequent re-sealing on compatible fluids. Buyers needing metric dimensions, higher pressure ratings or multi-lip designs must select a different part.

Questions about this item

What shaft diameter and housing bore does the 1.5 in by 2.716 in SKF 15204 seal fit?

The seal fits a 1.5 in shaft inside a 2.716 in housing bore with a .438 in overall width.

How do you install the CRW1 nitrile lip seal without damaging the spring or lip?

Lubricate the lip, press the metal case squarely into the bore using a flat tool on the outer case only, and avoid pushing on the spring or lip.

When should the seal be replaced given the 3,360 RPM and 10 psi limits?

Replace it if leakage appears, the lip hardens or cracks, or the shaft shows grooving, especially after sustained high-speed or high-temperature operation.
