Precision Withdrawal Sleeves for Secure Shaft Applications
Industrial withdrawal sleeves for secure dismounting of bearings—ideal for repair, service, and replacements.
AH 22 Withdrawal Sleeves
AH 22 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.
