    Type: Z1 – Z20


    Shaft: h6 or h8


    Hub: h7 or h8

Shanghai Metal Corporation is an expansion sleeve manufacturer and supplier.

It is an advanced basic component widely used internationally for mechanical connection under heavy loads. In the connection between wheels and shafts, it is a keyless coupling device that achieves load transmission by tightening high-strength bolts to produce pressure and friction between the containing surfaces.

Its principle and purpose are to generate a huge clamping force between the inner ring and the shaft, as well as between the outer ring and the wheel hub, through the action of high-strength tensile bolts, in order to achieve keyless connection between the machine parts and the shaft. When subjected to load, torque, axial force, or a combination of the two are transmitted through the combined pressure of the expansion sleeve with the machine parts and shaft, as well as the frictional force generated
