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.

Features and Benefits:
1、It can compensate the coaxiality error and realize automatic alignment.

2、It can bear radial load and axial load，and has good impact resistance.
3、Long service life.
4、Good anti vibration performance.
5、The double row spherical roller bearing with tightening sleeve can be installed at any position of the optical shaft without machining the locating shoulder.

Main applications of spherical roller bearing:

Papermaking machinery, reducer, railway vehicle axle, rolling mill gearbox bearing seat, rolling mill roller, crusher,vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer, vertical self-aligning bearing with seat.
