Due to the long-term transmission of large torque in the work of the expansion sleeve, it is easy to cause fatigue deformation of the metal, resulting in fatigue wear between the expansion sleeve and the fastener. At the same time, ... Read More

The expansion joint sleeve (referred to as the expansion sleeve) is an advanced basic component widely used in the world for mechanical connection under heavy load. A keyless coupling that transmits loads by pressure and friction. The expansion sleeve is ... Read More
