SKF 15005 Rotary Shaft Seal

This SKF 15005 rotary shaft seal fits a 1.5 in shaft and a 2.374 in bore with an overall width of .313 in. It uses a CRWA1 design with two nitrile rubber lips and a carbon steel spring. The case features an acrylic coating for installation protection.

Practical Limits of the CRWA1 Design

The seal handles a maximum pressure of 10 psi and a maximum surface speed of 6.74 mps. Rotational speed must stay at or below 3,360 RPM for reliable operation. It is rated for animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils. Exceeding these limits can cause premature lip wear or leakage.

Verify Shaft and Housing Dimensions Before Ordering

Confirm the shaft diameter is exactly 1.5 in and the housing bore is 2.374 in before purchase. The shaft surface must be smooth and free of nicks to prevent damage to the nitrile lips during installation. Ensure the application does not require pressure above 10 psi or speeds beyond 3,360 RPM.

Questions about this item

Should I choose the 1.5 in or 2.374 in version of the SKF 15005 shaft seal?

The SKF 15005 is a single part with a 1.5 in inside diameter and a 2.374 in outside diameter; both dimensions belong to the same seal, so you do not select between them.

What does the 3,360 RPM maximum rotational speed mean once the seal is installed in my engine?

It means the SKF 15005 can reliably seal a shaft spinning up to 3,360 RPM; beyond that speed the nitrile lips may overheat or lose contact, causing leaks.

How does the CRWA1 design code affect the pressure limit in practice?

The CRWA1 design with its twin nitrile lips and carbon-steel spring caps the seal at 10 psi, so it suits low-pressure splash or gravity-fed oil circuits but not pressurised systems.
