What is the difference between Timken adapter and withdrawal sleeves?

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. Timken adapter sleeves, which are supplied 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 Timken adapter & withdrawal Sleeves are available with oil supply ducts and distribution grooves.
