Hydraulic Withdrawal Sleeves for Effortless Dismounting
Hydraulic withdrawal sleeves offer oil-assisted dismounting—reduce labor time and bearing damage.
AOH 22 Hydraulic Withdrawal Sleeves
AOH 22 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.
