Industrial Grade Adapter Sleeves are easy to mount and require no additional location on the shaft. The Adapter Sleeves are commonly used components for locating bearings with a tapered bore onto a cylindrical seat as they can be used on smooth or stepped shafts. The Adapter Sleeves are used on smooth shafts; the bearing can be located at any position on the shaft. The Industrial Grade Adapter Sleeves when used on stepped shafts, together with an abutment ring, bearings can be accurately positioned axially and bearing dismounting is also facilitated.
