Adapter Sleeve used for Rolling Bearing           Inner Diameter: 50-470 - mm
Withdrawal Sleeve used for Rolling Bearing        Inner Diameter: 50-480 - mm

The adapter sleeve and withdrawal sleeve can fix bearings with tapered bore on the cylindrical crankshaft; The conical sleeve is helpful to the assembly and disassembly of bearing and can simplify the bearing supporting design of bearings.

 It is very common to use adapter sleeve, because it can fix bearings on the optical axis as well as step-shaped shaft. The withdrawal sleeve is easy for assembly without any supporting positioning devices on the shaft.

There must be a fixed pivot point on the axis, such as axial angle. The withdrawal sleeve does not embrace nuts, which should be ordered separately.
