Expansion sleeve (also known as expansion coupling sleeve, keyless bearing, etc.) is a keyless connection device, its principle and use is through the role of high-strength tension bolts, between the inner ring and the shaft, between the outer ring and the hub to produce a huge holding force, in order to achieve the keyless connection between the machine and the shaft. When the load is borne, the torque, axial force or composite load of the two is transmitted by the combined pressure of the expansion sleeve and the mechanical part and the shaft and the accompanying friction force.
