Adapters and adapter sleeves are used for securing tapered bore bearings on to the cylindrical shafts. They facilitate easy mounting and dismounting. They are suitable for both smooth and stepped shafts. The sleeves can easily adapt to the shaft diameter.
The adapter sleeves have slotted design and an external taper. They are usually not surface treated but oiled and are supplied with a lock nut and a locking device. They have an oil duct, distribution groove, and a threaded side.
For stepped shafts, they have two supply ducts and distribution grooves on the outer surface.
