Heavy-Duty Hydraulic Withdrawal Sleeves with ISO Fit
Oversized hydraulic withdrawal sleeves for large shaft diameters—fit demanding industrial environments.
AOH 241 Hydraulic Withdrawal Sleeves
AOH 241 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.
