AOH 240 Hydraulic Withdrawal Sleeves
AOH 240 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 Time by Up to 70%?
The AOH 240 series utilizes advanced hydraulic technology with strategically designed oil passages that create a thin oil film between the sleeve and bearing, dramatically reducing friction during mounting. This hydraulic advantage eliminates the need for excessive force, preventing bearing damage while cutting installation time by up to 70% compared to conventional methods. For maintenance teams managing critical equipment downtime, this efficiency translates directly to operational cost savings.
Available in 15 different models ranging from AOH24044 to AOH240/500, each sleeve is manufactured to exact specifications with a 1:12 taper ratio. The series features varying dimensions to accommodate different shaft sizes from 200mm to 480mm, with corresponding withdrawal nuts for complete system compatibility. Crafted in Taiwan with over three decades of manufacturing expertise, these hydraulic withdrawal sleeves offer industrial users the perfect balance of durability, precision, and functionality, making them an essential component for maintenance engineers and equipment manufacturers who demand reliable bearing mounting solutions.
