Bearing sleeves are a type of bearing accessory that allow a bearing with a tapered bore to be mounted onto a cylindrical or stepped shaft. There are two main types of bearing sleeves: adapter sleeves and withdrawal sleeves. Adapter sleeves are more commonly used, as they are easier to mount than withdrawal sleeves and require no additional location on the shaft
. They have an external taper and a slotted design, allowing bearings
to be mounted on stepped or cylindrical shafts. Withdrawal sleeves serve a similar purpose, allowing bearings to be mounted on stepped shafts. They are more difficult to mount however, because they must be located on the shaft using a nut or an end plate, which must be purchased separately from the sleeve. MRO Supply carries a wide range of adapter and withdrawal sleeves for many types of bearings. Don’t hesitate to ask our experts about which type of sleeve is best for your application.
