An adapter sleeve mounts a tapered bore bearing onto a cylindrical shaft. The assembly includes a tapered sleeve plus a lock nut and lock washer; tightening the nut produces the interference that holds the bearing in place. This makes the connection robust and removable, which suits gearboxes, conveyors and other process machinery.

For mounting a bearing with a tapered bore onto a cylindrical shaft, the NTN H series adapter sleeve provides a practical answer. Each unit combines a split sleeve with a lock nut and lock washer, so the bearing can be set precisely and taken apart without difficulty. Concentric running and resistance to axial movement depend on this interface, which makes the sleeve an important detail in power transmission assemblies. MR supplies this series with the application support needed to get the fit right.
Adapter sleeves from NTN let you mount tapered bore bearings on plain cylindrical shafts. The sleeve sits between shaft and bearing, and a lock nut or nut with lock washer pulls it tight to create a firm, concentric fit. This makes assembly and disassembly simpler and helps avoid damage to the bearing. MR Industrial Accessories LLC supplies these sleeves to industrial customers across the United States and Latin America.
