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.

How Does Hydraulic Installation with AH 39 Withdrawal Sleeves Reduce Bearing Mounting Time?
Hydraulic installation using CS AH 39 Withdrawal Sleeves can reduce bearing mounting time by up to 70% compared to conventional methods. The precision-engineered threads and 1:12 taper ratio allow for controlled hydraulic pressure application, eliminating the need for excessive force when mounting large bearings. This not only speeds up installation but also prevents bearing damage and ensures proper seating on the shaft. Our customers report significant maintenance downtime reduction and extended bearing life when using our withdrawal sleeves with hydraulic mounting techniques.
Our AH 39 series withdrawal sleeves simplify the bearing mounting process, especially for larger bearings where significant force is typically required to overcome mating surface friction. The precision-machined threads (both metric and trapezoid options) enable compatibility with hydraulic installation methods, dramatically reducing mounting effort while ensuring proper bearing alignment and fit. Made from premium-grade materials with exact dimensional tolerances, CS withdrawal sleeves provide the reliability and durability that professional maintenance engineers and equipment manufacturers demand for critical rotating equipment applications.
