Adapter Sleeves

Adapter Sleeves

The location of bearings with a tapered bore on cylindrical shaft studs can be carried out using easy-to-fit, reliable adapter and withdrawal sleeves.
Locknuts or shaft nuts can be used to locate bearings on shafts or adapter sleeves. Gradual loosening of nuts can be prevented using tab washers or retaining brackets. Shaft nuts are secured by means of force locking.

Adapter sleeves are suitable where bearings with a tapered bore are to be located on cylindrical shafts. They do not need to be secured on the shaft by any additional means. The bearings can be positioned at any point on smooth shafts.  If adapter sleeves are used with a support ring on stepped shafts, the bearings can be axially located to high accuracy. In addition, this gives simpler dismounting of the bearings.  Adapter sleeves comprise slotted adapter sleeves, locknuts and tab washers. For larger sizes, retaining brackets are used instead of tab washers.  The tensile strength of the material is at least 430 N/mm2. The outside surface of the sleeves has a taper of 1:12, in series H240 and H241 the taper is 1:30.
