22217 EC3 bearing has double-row rollers, the outer ring has a common spherical raceway. And the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious structure makes it have self-aligning performance, so it is not easy to be affected by the angle of the shaft.

It is suitable for occasions where the installation error or the shaft deflection causes the angle error. In addition to the radial load, the bearing can also withstand the axial load acting in both directions.

Spherical roller bearings have cylindrical and conical bores. The taper of the conical bore is 1:30 and 1:12. This conical bore bearing has an adapter sleeve or a withdrawal sleeve.
