External serration lock washer

Retaining rings are classified into hole retaining rings and shaft retaining rings, and their function is to limit axial movement of other parts. They are mostly formed by stamping sheet metal. Their functional cross-section is conical and they form "line contact" after assembly. For larger models, they are formed by winding wire and cutting off excess material, resulting in a regular rectangular cross-section, which forms "surface contact" after assembly.
