Perfect for industrial machinery applications requiring reliable bearing mounting.
AH 31 Withdrawal Sleeves
AH 31 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 Can Hydraulic Installation with AH 31 Withdrawal Sleeves Reduce Bearing Mounting Time by Up to 70%?
Hydraulic installation using CS AH 31 Withdrawal Sleeves eliminates the excessive force typically required when mounting large tapered bore bearings. By utilizing hydraulic pressure instead of mechanical force, maintenance teams can reduce installation time by up to 70% while minimizing the risk of bearing damage. Our precision-engineered sleeves with 1:12 taper ratio ensure even pressure distribution, making them ideal for applications where frequent bearing changes or precise mounting is critical. Contact us for customized hydraulic mounting solutions that can dramatically improve your maintenance efficiency.
Each AH 31 Withdrawal Sleeve is designed to simplify the bearing mounting process, particularly for larger bearings where significant force is required to overcome mating surface friction. The precision-machined sleeves allow for hydraulic installation methods that dramatically reduce mounting effort while ensuring proper alignment and fit. Compatible with appropriate withdrawal nuts (AN and HN series), our sleeves feature carefully engineered dimensions including optimized length (L), thread specifications, and weight considerations to meet the demanding requirements of heavy machinery applications in mining, metallurgy, paper mills, and other industrial sectors where reliable power transmission is essential.
