SKF 24865 Rotary Shaft Seal

The SKF 24865 is a rotary shaft seal built for grease-lubricated agricultural machinery. It fits a 2.5 in shaft and a 3 in housing bore with a .313 in width. The single nitrile lip handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils.

Capacity and operating limits

The seal runs up to 650 RPM and holds a maximum pressure of 3 psi. Its uncoated case and HM1 design code suit standard inch-dimension bores. It will not handle high-pressure hydraulic systems or speeds beyond the rated limit.

Replaces worn lip seals on farm equipment

This part upgrades a hardened or leaking nitrile seal on the same shaft and bore dimensions. The jump is worth it when the old lip no longer retains grease or excludes dirt at rated speeds. It is not for applications needing double-lip designs, spring-loaded lips or higher pressure ratings.

Questions about this item

Will the 2.5 in inside diameter match the shaft on my older agriculture machinery?

The seal is built to a 2.5 in inside diameter and a 3 in outside diameter, so it fits shafts made to those inch dimensions.

How can I verify the HM1 R nitrile seal is seated correctly after installation?

Check that the 0.313 in wide seal sits flush in the bore, the single lip contacts the shaft evenly, and the shaft turns freely up to 2,650 RPM without leakage.

Does the 24865 shaft seal come with a spring or installation tool, or must I buy them separately?

The spring material is listed as not applicable and no installation tool is included; only the nitrile rotary shaft seal itself is in the box.
