Heavy-Duty Withdrawal Sleeves for Rotating Assemblies
Large bearing withdrawal sleeves engineered for heavy load removal—ideal for mills and conveyors.
AH 240 Withdrawal Sleeves
AH 240 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.

AH240 Withdrawal Sleeves for Extra-Large Bearing Assemblies
Chin Sing’s AH240 withdrawal sleeves are designed for extra-large bearing systems, allowing safe and effective bearing removal under extreme load conditions. Their extended taper ensures consistent pressure along the shaft for smooth dismounting.
These sleeves are widely used in power plants, industrial kilns, and mining conveyors. Machined from high-strength steel and conforming to ISO and DIN standards, AH240 provides excellent grip and wear resistance.
Engineered for large-scale reliability, the AH240 sleeve ensures minimal disruption during bearing changes in critical systems.
