The retaining ring is also called the circlip, which is divided into the retaining ring for the hole and the retaining ring for the shaft, which acts as an axial limit and can prevent the axial movement of other parts. The forming process is mostly sheet punching, and the functional section is tapered. After assembly, it is mostly "linear contact". Some large-size models are made by wire winding and punching excess materials. The section is regular rectangular, and the surface after assembly is "surface". get in touch with".
Flat retaining ring: A separable, substantially flat washer whose inner or outer part is used as the outer ring or inner ring rib of a radial cylindrical roller bearing.
Oblique retaining ring: A separable ring with an "L"-shaped cross-section, the outer part of which acts as the inner rib of a radial roller ball bearing.
Middle retaining ring: A separable ring in two or more rows of roller bearings, used to separate and guide each row of rollers.
The rib is a narrow shoulder that is parallel to the rolling direction and protrudes from the surface of the raceway. It is used to support and guide the rolling element and keep it in the bearing.
