SKF 99112 Wear Sleeve Shaft Range

The SKF 99112 wear sleeve fits shaft diameters from 28.52 to 28.63 mm and is made from chromium-plated stainless steel. It provides a durable sealing surface for heavy industrial applications and withstands temperatures up to 225 degrees F. The flange diameter measures 38.1 mm and the overall width is 11.13 mm.

Replaces Worn Shaft Surfaces

This sleeve restores the sealing surface on a damaged shaft without machining or replacing the shaft itself. The jump is worthwhile when the shaft is otherwise sound but the contact area is grooved or corroded beyond what a standard seal can handle. Installation presses the sleeve onto the shaft to create a new running surface for the seal.

Suits Maintenance Teams With Metric Shafts

Mechanics servicing heavy industrial equipment with shafts in the 28.52 to 28.63 mm range can use this sleeve to extend component life. It is not intended for shafts outside that diameter range or for applications exceeding the 225 degree F temperature limit. Builders needing a different shaft size or a non-metallic sleeve should look at other options.

Questions about this item

What shaft diameter range does the SKF 99112 wear sleeve fit?

The SKF 99112 wear sleeve fits shaft diameters from 28.52 mm to 28.63 mm, with an outside diameter tolerance of +/- 1.6 mm.

How is the SKF 99112 wear sleeve installed on the shaft?

Press the chromium-plated stainless steel sleeve onto the clean shaft until the 7.95 mm width on shaft is fully seated; the step often missed is ensuring the flange diameter of 38.1 mm sits square against the shoulder.

When should the SKF 99112 wear sleeve be replaced in heavy industrial use?

Replace the sleeve if the 0.28 mm wall thickness shows wear grooves, if operating temperatures exceed 225 Degrees F, or if the 11.13 mm overall width becomes distorted.
