Adapter sleeves are used to fasten bearings with a conical opening on machine shafts. They make it easy to build and dismantle bearings and simplify the bearing structure. Their taper on the pitch-surface generator is 1:12 or 1:30. They can be regular or with hydraulically assisted assembly and disassembly.



H adapter sleeves are offered in a set with a nut and locking washer. ZUM manufactures adapter sleeves with a diameter of up to 800 mm (small diameter of the cone) for metric and inch shafts. Dimensions of sleeves for metric shafts comply with the DIN 5415 and ISO 2982-1 standards.



Assembly and disassembly of large bearings is facilitated by a hydraulic method. Adapter sleeves have grease grooves on the external surface, and sometimes also in the opening and they also have appropriate screwed openings to connect pressure conduits of the oil pump.
