Product Identity

The SKF 12582 is a rotary shaft seal designed for grease-lubricated agricultural machinery. It suits maintenance teams replacing worn seals on equipment shafts where the inside diameter measures 1.979 in and the outside diameter measures 2.25 in.

Critical Specification

The lip material is nitrile rubber rated for a maximum pressure of 10 psi and a maximum rotational speed of 2,986 RPM. This single limit decides whether the seal matches the operating conditions of the shaft being repaired.

Installation Notes

The seal has an overall width of .25 in and an uncoated case, so it presses into the housing without special tools. A common issue is damaging the single lip during installation if the shaft surface has burrs or the seal is cocked in the bore.

Questions about this item

How does the 1.979 in inside diameter translate when the seal is installed on a shaft?

The 1.979 in inside diameter matches the shaft outside diameter, so the nitrile lip seats directly on a 1.979 in shaft with the 0.25 in width providing the contact face.

What does the 10 psi pressure limit mean for the HM14 seal in service?

The 10 psi maximum pressure caps the differential the single nitrile lip can hold back; above that the lip can roll or extrude, so the seal suits only low-pressure splash or vented housings.

What bore and shaft dimensions are needed to mount this 2.25 in OD seal?

Press the 2.25 in outside diameter into a 2.25 in bore and run a 1.979 in shaft through the 1.979 in inside diameter; the 0.25 in width sets the axial space required.
