Bearing Adapter Sleeve

An adapter sleeve is a cylindrical sleeve that is used to mount bearings with a tapered bore onto a shaft with a cylindrical outer diameter. It is typically made of steel and has a tapered bore on the inner surface that matches the taper of the bearing's inner ring. The adapter sleeve is used to facilitate the mounting and dismounting of bearings on a shaft. It is installed by sliding it onto the shaft and tightening the locknut to secure it in place. The tapered bore of the sleeve allows it to be easily aligned with the tapered bore of the bearing, ensuring a proper fit. The adapter sleeve also provides a larger bearing surface area on the shaft, which helps to distribute the load more evenly and reduce the risk of shaft damage. It can also be used to compensate for any slight misalignment between the shaft and the bearing. Overall, the adapter sleeve is a crucial component in the installation and operation of bearings, as it allows for easy mounting and dismounting, improves load distribution, and helps to ensure proper alignment.
