The key elements of adapter sleeves are tapered adapter bush, locknut, lock washer. Adapter sleeves are axially slotted sleeve with cylindrical bore, tapered outside surface and male screw thread at small end used with locknut and lock washer for mounting of bearings with tapered bore on cylindrical outside surface of shaft. It is also call pull-type sleeve. Adapter sleeves are the most commonly used components for locating bearings with a tapered bore onto a cylindrical seat as they can be used on smooth or stepped shafts. They are easy to mount and require no additional location on the shaft. When adapter sleeves used on smooth shafts, the bearing can be located at any position on the shaft. When used on stepped shafts, together with an abutment ring, bearings can be accurately positioned axially and bearing dismounting is facilitated.
