This type of arrangement where bearings are mounted on adapter sleeves and smooth shafts is probably the most popular arrangement especially for smaller bearings and provides an economic solution.
Advantages
–
Commercial drawn shafting to tolerance h9 can be used without further machining.
–
The shafts have maximum strength as there are no steps or undercuts to weaken them.
–
The bearing can be mounted at any position along the shaft.
–
The force to drive the bearing up on the sleeve is some 40 % lower than for other types of sleeve mounting as friction only occurs between two mating surfaces.
–
Bearing clearance can be adjusted, within certain limits, to the operating conditions during mounting.
Applications
–
The support of long shafts at more than two positions.
–
The support of shafts on which other components are also attached by clamping or tensioning devices so that machining is not required.
–
Bearing arrangements where the final position of the bearing cannot be accurately prescribed prior to mounting.
