Adapter Sleeves

Product Description

The adapter sleeves are fixing sleeves, normally used to mount spherical bearings onto mechanical shafts. Based on information made available from NTN, the adapter sleeves in question are threaded steel sleeves that feature a slotted straight bore with a finely ground tapered surface on their outer circumference. The straight bore fits onto a round shaft, while the tapered outer surface is designed to accept bearings that have an inner ring with a matching taper. The bearing and sleeve can be fixed anywhere along the length of a round shaft by tightening a lockwasher onto the sleeve’s threads, which, in turn, compresses the slotted sleeve thereby fixing it in place.
