AOH 22 Hydraulic Withdrawal Sleeves
AOH 22 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 can hydraulic withdrawal sleeves reduce equipment downtime during bearing replacement?
The AOH 22 Hydraulic Withdrawal Sleeves significantly reduce maintenance downtime by enabling quick and damage-free bearing installation and removal. Unlike conventional methods that may require excessive force, these sleeves utilize pressurized oil injection through specially designed passages to create a thin oil film between contact surfaces, allowing bearings to slide off shafts effortlessly. This hydraulic dismounting technique can reduce bearing replacement time by up to 70% while minimizing the risk of damage to expensive components. Contact us for a consultation on implementing these sleeves in your maintenance procedures.
Available in multiple models including AOH2236 through AOH2264, these metric withdrawal sleeves are manufactured to exacting standards with a 1:12 taper ratio. Each model is compatible with specific withdrawal nut numbers and features precise dimensional specifications to ensure optimal performance. The sleeves' hydraulic design eliminates the need for excessive force during bearing mounting operations, reducing the risk of component damage while extending equipment service life. Trusted by bearing manufacturers and heavy machinery industries worldwide, CS AOH 22 series represents Taiwan's commitment to manufacturing excellence in industrial bearing components.
