Industrial Hydraulic Withdrawal Sleeves with Oil Injection
Hydraulic withdrawal sleeves with pressure oil ducts—streamline the dismounting process.
AOH 30 Hydraulic Withdrawal Sleeves
AOH 30 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.

AOH-30 Hydraulic Withdrawal Sleeves for Large Bearings
Chin Sing’s AOH-30 series hydraulic withdrawal sleeves are engineered to simplify bearing removal from shafts in high-load applications. Their integrated oil grooves allow uniform pressure distribution for smooth, damage-free disassembly.
These sleeves are widely used in marine engines, cement plants, and heavy-duty drives where reliability and service speed are critical. Each sleeve is ISO/DIN compliant and built from hardened steel for long life and precision fit.
Rely on AOH-30 sleeves when dismounting large bearings under tight tolerances and high axial force conditions.
