Application Scope

The SKF 15194 is a rotary shaft seal designed for equipment with a 1.5 in shaft diameter and a 2.623 in housing bore. It suits maintenance teams and rebuilders who need a reliable lip seal for rotating assemblies in industrial or automotive drivelines.

Build Integration

The seal presses into a standard inch-dimension bore and uses an acrylic-coated case to resist installation damage. Its single nitrile lip handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils without requiring a separate sleeve or special surface finish.

Sustained Operation

A carbon-steel garter spring maintains lip contact up to 3, 360 RPM and a surface speed of 6.74 mps while the design pressure limit stays at 10 psi. The nitrile compound resists heat aging during continuous duty, so leak-free performance persists through extended run cycles rather than only during brief test spins.

Questions about this item

How long will the 10 psi pressure rating hold before the seal starts to weep?

The seal is rated for a maximum of 10 psi continuous pressure. Exceeding this limit is the first factor that causes leakage under sustained operation.

Does the NBR lip material handle the heat at 3,360 RPM without hardening?

At the maximum 3,360 RPM the lip sees a surface speed of 6.74 m/s. NBR is suitable for this speed range, but prolonged high-temperature running can accelerate hardening.

Will the 1.5 in inside diameter fit my shaft without a sleeve?

The seal requires a shaft diameter of exactly 1.5 in. If your shaft is worn or a different size, you must install a correctly sized sleeve before fitting the seal.
