Withdrawal Sleeves / Hydraulic Withdrawal Sleeve


 

WITHDRAWAL SLEEVE :
AH, AHX adapt themselves to the shaft diameter, while wider diameter tolerances can also be permitted than for the seat of a bearing with a cylindrical bore. Used to fix bearings with a tapered bore on supported shafts(lean). With Withdrawal Sleeve the shaft must have a thread so the nut can move the sleeve against the bearing. Lock nuts or end plates are not supplied with withdrawal sleeves. KM or HM Lock nuts with appropriate locking devices are suitable, but must be ordered separately.

Suffixes Since 1997, there have been withdrawal sleeves with the suffix G. The G indicates a change of thread size. With withdrawal sleeves and adapter sleeves having different thread sizes, attempts have been made to standardize them. These standardization efforts are inspired by a desire to reduce nut variation.
