SPHERICAL ROLLER BEARINGS INTRODUCTION
Spherical roller bearings consist of an outer ring with spherical raceways and an inner ring with double raceways, one or two cages and a set of spherical rollers. Since the center of the spherical raceway of the outer ring coincides with the center of the bearing, it has self-aligning performance. This kind of bearing can adjust the angle error or deflection caused by the angle of the shaft and the bearing box or the bending of the shaft. Spherical roller bearings have a high load-bearing capacity and can bear radial load and shaft load in two directions. It is particularly suitable for carrying heavy loads and shock loads, but this type of bearing allows a lower limit speed. The allowable alignment angle of spherical roller bearings under normal conditions is 1°~2.5°. If this type of bearing has a seal, the function will be reduced.
