Spherical roller bearings have double row rollers, the outer ring has one shared spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious construction makes it self-aligning, so it is not susceptible to the angle error of the shaft and the bearing housing, or the bending of the shaft. It is suitable for installation errors or shaft deflections that cause angular errors. In addition to being able to withstand radial loads, the bearing can withstand axial loads in both directions.
The spherical roller bearing has two kinds of inner and outer holes, and the conical tapered hole has a taper of 1:30 and 1:12. The conical inner bore bearing is equipped with an adapter sleeve or a withdrawal sleeve. The tapered bore self-aligning ball bearing can be easily and quickly assembled on the optical axis or step machine shaft.
