Withdrawal Sleeves

Adapter sleeves are used to fix tapered bore bearings to a shaft. They make shaft mounting and dismounting easy because they do not require additional fixing or locating devices on the shaft; they can be fixed anywhere on the shaft. Adapter sleeves typically come with a lock nut and lock washer and have a slot at the narrow end the washer slips into and the nut to thread behind for tightening. Also known as tapered sleeves, adapter sleeves provide a true fit along a shaft, which gives the bearing a longer life. They are useful in applications where balancing is important, such as with large fans.
