Spherical Roller Bearing 22348CA NSK Woodworking Machinery

Spherical roller bearing has two rows of rollers, which mainly bear radial load, but also can bear axial load in any direction. High radial load capacity, especially suitable for heavy loads or vibration loads, but can not withstand pure axial load. The raceway of the outer ring of this kind of bearing is spherical, so it has good aligning performance and can compensate the coaxiality error.

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.

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 uses:Paper making 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.
