[0002] A cylindrical roller bearing refers to a radial rolling bearing with cylindrical rollers as rolling elements. The internal structure of a cylindrical roller bearing uses rollers arranged in parallel, and a spacer retainer or spacer block is installed between the rollers to prevent the inclination of the rollers or mutual friction between the rollers, effectively preventing the increase of rotational torque. The raceways and rolling elements of a cylindrical roller bearing are geometrically shaped. After improved design, it has a higher load-carrying capacity. The new structural design of the ribs and the roller end faces not only improves the axial load-carrying capacity of the bearing, but also improves the lubrication conditions in the contact area between the roller end faces and the ribs, improving the service performance of the bearing.
