Sleeves are used to mount bearings with a tapered bore.Generally, bearings used in Housings are mounted on straight or stepped shafts by means of an Adapter Sleeve – the most popular Sleeve choice due to their versatility and easy mounting characteristics or, with a withdrawal sleeve, which can be used on stepped shafts only. These Sleeves are available in appropriate sizes for the range of bearings used in housings etc.Adapter Sleeves are used to secure bearings with a tapered bore onto cylindrical shaft seatings. They facilitate bearing mounting and dismounting and often simplify bearing arrangement design.
Adapter Sleeves are the more popular choice of sleeve as they enable bearings to be mounted on smooth shafts, they are easier to mount in comparison to a Withdrawal Sleeve and require no additional location on the shaft. Adapter Sleeves, which are suppllied with a lock nut and locking washer, have a slotted design and an external taper.
Bearings on Withdrawal Sleeves must be mounted against a fixed abutment. Withdrawal Sleeves are slotted, have an external taper, and are also coated with a preservative.
Larger Adapter Sleeves are available with oil supply ducts and distribution grooves.
