Architecture description: Symmetrical spherical roller, two hardened steel stamped cage, inner ring without retaining edge and with a cage guided by the middle retaining ring.
Advantages and features: The middle stop ring near the outer ring can improve the lubrication of the contact between the roller end face and the stop ring, its role is to reduce bearing friction, help guide the roller in the non-load area, and assist the roller into the load area, while the length of the roller increases, so the rated load has been greatly improved. Usually the rated load can be increased by 20% ~ 35%.
