The retaining ring of the rolling bearing is equivalent to a movable retaining edge, which is used for retaining the rollers and is convenient for installation. The structure of the retaining ring includes a flat retaining ring, an inclined retaining ring and a middle retaining ring.
Flat retaining ring: A separable substantially flat washer whose inner or outer portion serves as a radial cylindrical roller bearing outer or inner ring rib. Oblique retaining ring: a separable ring with an 'L'-shaped section, the outer part of which acts as an inner rib of a radial roller ball bearing. Intermediate Ring: A separable ring in a two or more row roller bearing that separates and guides each row of rollers. Ribs are narrow shoulders that protrude from the raceway surface parallel to the rolling direction to support and guide the rolling elements and keep them in the bearing.
