AOH 241 Hydraulic Withdrawal Sleeves
AOH 241 Hydraulic Withdrawal Sleeves for metric shafts, for metric spindle. The withdrawal sleeves is one of the more popular and common used industrial sleeves. It can be used to mount bearings dismount with a tapered bore on the cylindrical seat of stepped shafts. Hydraulic bearing sleeves facilitate mounting on large bearings. An oil pump is required to inject pressurized oil. There are oil passages on the threaded side and grooves on the outer surface which can be filled with internal oil according to requirements. It is convenient for installation and the disassembly of components.

How Does the Hydraulic System in AOH 241 Sleeves Prevent Bearing Damage During Disassembly?
The AOH 241 series features specialized oil passages and distribution grooves that allow pressurized oil to create a thin film between the sleeve and bearing, effectively breaking the metal-to-metal contact. This hydraulic mechanism reduces the extraction force by up to 90%, preventing deformation and microscopic damage to bearing races during disassembly. For heavy machinery with expensive bearings, this translates to significant maintenance cost savings and extended component life. Contact us for technical specifications tailored to your application requirements.
Available in fifteen different specifications ranging from AOH24144 to AOH241/500, our hydraulic withdrawal sleeves accommodate shaft diameters from 200mm to 480mm. Each model is manufactured to exacting standards with appropriate thread specifications and compatible with corresponding withdrawal nuts (HN series). The hydraulic mechanism significantly reduces the force required for bearing removal, preventing damage to valuable components and extending operational lifespan. These sleeves are particularly valuable for heavy machinery applications where frequent maintenance requires reliable bearing dismounting solutions.
