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.

How Can AH 3 Withdrawal Sleeves Simplify Your Bearing Installation Process?
AH 3 Withdrawal Sleeves eliminate the complexity of fitting tapered bore bearings onto stepped shafts by providing a precision-engineered mounting interface. With a standardized 1:12 taper ratio and metric threading compatibility, these sleeves reduce installation time by up to 40% while ensuring proper bearing alignment. For larger applications, they're fully compatible with hydraulic mounting methods, significantly reducing the force required and minimizing the risk of bearing damage during installation. Contact us for a consultation on how our withdrawal sleeves can optimize your specific bearing mounting challenges.
Our AH 3 Withdrawal Sleeves are engineered for applications where bearings need to be precisely fixed onto shafts through a fiber web or endplate. For larger bearings that require greater force to overcome mating surface friction, these sleeves can be paired with hydraulic installation methods to significantly simplify the mounting process. Each sleeve is manufactured to exact specifications with attention to critical dimensions including length (L), width (b), and appropriate thread sizes, ensuring consistent performance across industrial applications. Complete technical specifications, including weight and compatible withdrawal nut information, are available for download to support your engineering and maintenance requirements.
