[0002] The spherical roller bearing has double-row rollers, the outer ring has a common spherical raceway, and the inner ring has two raceways that are tilted at an angle relative to the bearing axis. This ingenious structure gives it automatic self-aligning performance, so it is not easily affected by the angle between the shaft and the bearing box seat or the shaft bending, and is suitable for occasions where the angle error is caused by installation error or shaft deflection. In addition to being able to withstand radial loads, the bearing can also withstand bidirectional axial loads. The inner hole of the spherical roller bearing is cylindrical and conical, and the taper of the conical taper hole is 1:30 and 1:12. This tapered inner hole bearing is equipped with a tightening sleeve or a withdrawal sleeve, so that the tapered inner hole aligning ball bearing can be easily and quickly assembled on the optical shaft or the step machine shaft.

After the balls rotate for a certain period of time, a higher temperature will be generated on the surface of the balls, and the temperature will be transmitted to the entire bearing, causing the bearings to overheat, which will in turn affect the performance and service life of the bearings.
