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.
Stamped steel reinforced cage (suffix E, very few in China).
Stamped steel plate cage (suffix CC), glass fiber reinforced polyamide 66 cage (suffix TVPB), machined brass two-piece cage (suffix MB).
Machined brass integral cage (suffix CA), stamping steel cage for vibration occasions (suffix JPA).
Brass cage for vibrating occasions (suffix EMA). The same structure, bearing on the code may be different.
1. Low rotation, impact resistance, vibration resistance;
2.With automatic centering function, that is, the inner ring axis relative to the outer ring axis has a large tilt (generally within 3 degrees) can still operate normally;
3. Mainly bear a large radial load, but also can bear small axial load;
4. With high rolling contact fatigue strength;
5. With high hardness and high mechanical strength, the product is high wear resistance;
6. High dimensional stability of the product.
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.
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.
