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.

How do AOH 30 Hydraulic Withdrawal Sleeves reduce bearing installation time and damage risk?
The integrated oil passage system in our AOH 30 series creates a thin oil film between the sleeve and bearing, reducing friction by up to 90% during mounting/dismounting. This hydraulic advantage eliminates the need for excessive force that often leads to premature bearing damage. Maintenance teams report installation time reductions of 40-60% while significantly extending bearing service life. Request our technical specifications to calculate the efficiency gains for your specific applications.
Our comprehensive AOH 30 series ranges from AOH3032 to AOH30/500, accommodating shaft diameters from 150mm to 480mm with a consistent 1:12 taper ratio. Each sleeve is engineered with exact dimensional specifications and compatible with corresponding withdrawal nuts (AN/HNL series) for a complete mounting system. The hydraulic design eliminates the need for excessive force during bearing maintenance operations, extending component lifespan while reducing downtime and maintenance costs in critical industrial applications.
