In the fields of automobile, motorcycle and other vehicle manufacturing, locking devices are commonly used to connect engine output shafts, transmission shafts, gears and other components to achieve power transmission.

locking device is a keyless coupling device, which works by using high-strength tension bolts to generate a huge clamping force between the inner ring and the shaft, and between the outer ring and the wheel hub, in order to achieve keyless coupling between the components and the shaft. Widely used in heavy machinery, wind power generation, packaging machinery, printing machinery, CNC machine tools, automation equipment and other fields.
