SKF High Precision Bearing 22220E C3 Spherical Roller Bearing

The spherical roller bearing has a double row of rollers, with one common spherical raceway in the outer ring and two raceway in the inner ring and 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 of shaft and bearing box on the error or shaft bending, suitable for installation error or shaft deflection caused by Angle error. The bearing can bear radial load as well as bidirectional axial load.

The inner hole of the self-aligning roller bearing has two kinds: cylindrical and conical, and the taper of the conical cone hole is 1:30 and 1:12. This kind of conical inner hole bearing is equipped with a tight sleeve or a disconnecting sleeve, so that the self-aligning ball bearing with the conical inner hole can be conveniently and quickly assembled on the optical shaft or the stepped machine shaft.
