Withdrawal Sleeves with Exact Fit for Shaft Tapers
Tapered withdrawal sleeves compatible with cylindrical shafts—ensure precision fit and secure hold.
AH 39 Withdrawal Sleeves
AH 39 Withdrawal Sleeves can mount a tapered bore bearing on a round stepped shaft, which is one of the more popular and commonly used industrial sleeves. Generally, the withdrawal sleeve was pressed into a bearing inner bore to fix it on the shaft through a fiber web or endplate. For larger bearings, when it was pressed against the bearing bore, a larger force is required to overcome the friction of the mating surface. Hydraulic installation can simplify this process by a withdrawal sleeve.
