  Non standard spherical roller bearings

The self-aligning roller bearing has two rows of rollers. The outer ring has one common spherical raceway, and the inner ring has two raceways, which are inclined to form an angle with respect to the bearing axis. This ingenious structure enables it to have automatic centering performance, so it is not vulnerable to the influence of the angle between the shaft and the bearing housing on the error or shaft bending. It is suitable for the occasion where the angle error is caused by installation error or shaft deflection. The bearing can not only bear the radial load, but also bear the axial load of two-way action. The inner holes of the self-aligning roller bearings are cylindrical and conical, and the taper of the conical hole is 1:30 and 1:12. The conical inner hole bearing is equipped with a locking sleeve or a withdrawal sleeve, so that the tapered inner hole self-aligning ball bearing can be conveniently and quickly assembled on the smooth shaft or the ladder machine shaft.
