The CCJA type is a spherical roller bearing for vibrating screens. It consists of an outer ring, an inner ring, asymmetric rollers and a cage. There is a cage on the upper part of the inner ring, and asymmetric rollers are installed on the cage. The upper part of the cage is the outer ring; the bottom of each cage is equipped with a slope structure. The height of the slope structure is 0.4~0.6 times the thickness of the cage. The angle of the slope structure is 10~15°. The cage is an inner-guided MB spherical roller bearing. Cage or externally guided MB spherical roller bearing cage. The spherical roller bearing for vibrating screens of this utility model is designed with a slope structure at the bottom of each cage, which can effectively store lubricating oil (grease). Between the two cages, it is more convenient for the lubrication inside the bearing. It can prevent the bearing from dry friction at the bottom of the two cages under high-speed, vibration, and impact conditions, which greatly improves the service life of the cage. It improves the life reliability of the new vibrating screen bearing and meets the needs of customers to the greatest extent.
