AOH 32 Hydraulic Withdrawal Sleeves
AOH 32 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 Does the Hydraulic System in AOH 32 Sleeves Reduce Equipment Damage During Bearing Removal?
The AOH 32 Hydraulic Withdrawal Sleeves utilize pressurized oil injection through strategically placed oil passages and surface grooves to create an even hydraulic film between the sleeve and bearing. This eliminates metal-to-metal contact during dismounting, preventing scoring and surface damage to expensive components. When pressure is applied, the oil film reduces friction by up to 90%, allowing for controlled, force-distributed removal that protects both the bearing and shaft from the warping and stress damage commonly experienced with mechanical removal methods. Contact us for detailed specifications on implementing this damage-prevention system in your equipment.
Available in 16 distinct models ranging from AOH3232 to AOH32/500, these withdrawal sleeves are engineered with a 1:12 taper ratio for optimal performance. Each model is meticulously designed with specific dimensions to accommodate various shaft sizes from 150mm to 480mm, featuring appropriate thread specifications and compatible withdrawal nut numbers. The hydraulic mechanism eliminates the need for excessive force during bearing removal, protecting valuable components while reducing maintenance downtime in critical industrial applications. For large bearing installations, these sleeves provide an indispensable solution that enhances operational efficiency and extends equipment service life.
