The most widely used parts for locating tapered bore bearings onto a cylindrical seat are adapter sleeves since they may be utilized on both plain and stepped shafts.
They don't require any extra space on the shaft and are simple to install. The bearing can be found anywhere on a plain shaft when it is used in that manner. paired with an L-shaped spacer ring and applied to stepped shafts.Mounting and unmounting the bearing is made easier by the ability to precisely position the bearing axially.
