The retaining ring is divided into a hole retaining ring and a shaft retaining ring

The retaining ring is divided into a hole retaining ring and a shaft retaining ring, which have a limiting effect and can prevent other parts from moving axially. The forming process often uses sheet metal punching, with a conical functional section and a "linear contact" after assembly. Some large-sized models are made by wire winding and punching excess materials, with a regular rectangular cross-section and "surface contact" after assembly.
