SKF 24982 Rotary Shaft Seal

The SKF 24982 is a CRWA1 design rotary shaft seal built for retaining lubricants and excluding contaminants in rotating equipment. It suits maintenance technicians and engineers servicing pumps, gearboxes or motors where a 2.5 in shaft runs at speeds up to 2, 640 RPM.

Press-fit installation with acrylic-coated case

The seal installs by pressing the acrylic-coated metal case into a 3.5 in bore until flush; the coating helps seal minor housing imperfections. Damage typically occurs if the lip is folded back during insertion or if the carbon-steel garter spring is dislodged by hammer blows instead of a proper driver.

Twin nitrile lips handle 10 psi continuous pressure

Two nitrile rubber lips share the sealing load, limiting heat build-up during sustained operation at up to 8.81 mps surface speed. The design resists animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils without hardening, maintaining contact pressure throughout extended duty cycles.

Questions about this item

How can I verify the seal is functioning correctly after installation?

Check for zero fluid leakage at the 2.5 in shaft interface and confirm the equipment runs below 2,640 RPM without abnormal heat or noise at the lip.

What components are included and what must be sourced separately?

The box contains the SKF 24982 rotary shaft seal with CRWA1 design, nitrile rubber lips, carbon steel spring and acrylic-coated case; installation tools, lubricant and the mating shaft or housing are not included.

Which size or version should I select for my application?

Choose this 24982 model only when the shaft diameter is 2.5 in, the bore is 3.5 in, the width is .438 in, the fluid type matches oils, gasoline, greases or hot water, and the speed stays under 2,640 RPM.
