Roller bearing is a kind of rolling bearing, which is widely used in modern machinery. It relies on the rolling contact between the main components to support the rotating parts. Roller bearings are now mostly standardized. The roller bearing has the advantages of small starting torque, high rotation accuracy and convenient selection.

    Thrust roller bearings include products using cylindrical rollers and products using spherical rollers. Although this type of bearing can only bear axial load, it has the characteristics of being suitable for bearing heavy loads and high shaft rigidity. Among them, the thrust spherical roller bearing has a bulge in the middle of the roller and has a centering function. Therefore, this kind of bearing is not affected by installation errors and shaft deflection. The standard configuration of the cage is a machined brass product; the E-type product uses a stamping processing cage, which has the characteristics of large load capacity.

    Spherical roller bearings, as shown in the figure, are available in types EA, C, CD, and CA with high load capacity design. In design, EA type, C type, CD type are stamping cage, CA type is copper alloy car cage. EA type bearings have the characteristics of high load capacity and low torque.

    In terms of design, the raceway surfaces of the inner ring and outer ring of the tapered roller bearing and the conical apex of the roller converge at a point on the central axis of the bearing. The truncated cone-shaped roller is assembled in the bearing as a rolling element and guided by the large rib of the inner ring.

    Cylindrical rollers and raceways are in line contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the retaining edge of the ring is small, which is suitable for high-speed rotation.
