Spherical roller bearings have two rows of spherical rollers, the outer ring has a common concave spherical raceway, and the inner ring has two concave raceways inclined at a certain angle to the bearing axis. The curvature center of the outer ring raceway and The bearings are aligned in the center. Spherical roller bearings are self-aligning. In addition to bearing radial loads, they can also bear bidirectional axial loads and their combined loads. They have a large load carrying capacity and good vibration and shock resistance.
Spherical roller cage description:
CC: Two-piece steel stamping cage, inner ring without ribs and with a middle ring with or without inner ring guide. Compared with CA type bearings, it bears a larger load and has a longer life.
CA: Integral machine-cut brass cage, with ribs on both sides of the inner ring, and a middle ring guided by the inner ring. This type of bearing has a higher limit speed and relatively low noise.
MB: Two-piece machine-cut brass solid cage, with ribs on both sides and middle of the inner ring, similar in performance and characteristics to the CA type, but with a lower rated load.
E: The latest international design, it adopts symmetrical spherical rollers, two pieces of quenched steel stamping cage, inner ring without ribs and a middle ring with or without inner ring guide. The middle retaining ring close to the outer ring can improve the lubrication of the contact between the end face of the roller and the retaining ring. Its function is to reduce the friction of the bearing, help guide the roller in the non-load area, and assist the roller to enter the load area while rolling The sub-length is increased, so the rated load has been greatly improved. It can usually be increased by 25%-35%.
