Product Description

 

21311E 21311EK Self-Aligning Roller Bearing Spherical Roller Bearing.
The self-aligning roller bearing has double row rollers, the outer ring has one common spherical raceway, and the inner ring has two raceways, which are inclined at an angle relative to the bearing axis. This ingenious structure makes it self-aligning, so it is not easy to be affected by the angle between the shaft and the bearing housing seat on the error or shaft bending. It is suitable for the occasion of angle error caused by installation error or shaft bending. The bearing can not only bear the radial load, but also the axial load of two-way action.

The inner bore of self-aligning roller bearing has two kinds: cylindrical and conical. The taper of conical bore is 1:30 and 1:12. This kind of tapered bore bearing can be easily and quickly assembled on the optical shaft or the stepped shaft by using the tightening sleeve or the withdrawal sleeve.
