Standard Withdrawal Sleeves for Easy Bearing Dismounting
Withdrawal sleeves for tapered bore bearings—easy to install and remove without damaging shaft or housing.
AH 3 Withdrawal Sleeves
AH 3 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 sleeves are pressed into a bearing inner bore to fix it on the shaft through a fiber web or endplate. For larger bearings, when it is 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.
