CS AOH 23 Hydraulic Withdrawal Sleeves - Professional Metric Bearing Mounting Solution
CS AOH 23 Hydraulic Withdrawal Sleeves facilitate easy mounting and dismounting of large bearings with tapered bores on cylindrical shafts. Featuring oil passages and precision engineering, these Taiwan-manufactured sleeves ensure efficient bearing installation across multiple industrial applications. Available in 9 metric sizes from AOH2332 to AOH2356.
AOH 23 Hydraulic Withdrawal Sleeves
AOH 23 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 technology reduce bearing installation damage and downtime?
The AOH 23 Hydraulic Withdrawal Sleeves utilize pressurized oil channels to create a thin oil film between contact surfaces, reducing mounting force by up to 90%. This hydraulic principle eliminates the need for hammering or excessive force that often leads to premature bearing failure. For maintenance teams handling critical equipment, this translates to faster servicing, extended component lifespan, and significantly reduced downtime—ultimately saving thousands in operational costs. Request specifications to see how our hydraulic mounting solution can optimize your maintenance procedures.
Manufactured in Taiwan with over 33 years of industry expertise, CS Hydraulic Withdrawal Sleeves are crafted to meet the exacting standards of professional bearing applications. The hydraulic functionality eliminates the need for excessive force during installation and removal processes, preventing potential damage to valuable bearings and shafts. Each sleeve is compatible with specific withdrawal nuts (such as AN36 to HN62 series) and features precise threading specifications to ensure secure mounting. The robust construction and meticulous engineering of these sleeves make them essential components for maintenance teams and equipment manufacturers dealing with heavy machinery where reliable bearing performance is critical.
