Spherical roller bearings have double rows of rollers, the outer ring has a common spherical raceway, the inner ring has two raceways and tilted to 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 shaft and bearing box angle error or shaft bending, suitable for installation error or shaft deflection caused by the angle error of the occasion. The bearing can withstand not only radial load, but also axial load in both directions.

Spherical roller bearing 21306 applications:
paper making machinery, speed reduction devices, railroad vehicle axles, rolling mill gear box bearing housings, rolling mill rolls, crushers, vibrating screens, printing machinery, woodworking machinery, various types of industrial speed reducers, vertical spherical bearings with seats.
Advantages of spherical roller bearing 21306.
One, large radial load capacity. Easy to install, can be directly installed or use the tightening sleeve, assembly cylinder installed in the cylindrical shaft.
Second, can withstand a certain axial load. Spherical roller bearing 21306 outer ring raceway is spherical shape can withstand large radial load. Therefore, it has the performance of centering, not shaft and bearing box misalignment or shaft deformation deflection, can compensate for coaxiality error.
Third, has two spherical roller, outer ring has a common concave spherical raceway, inner ring has two and bearing axis tilt an angle concave raceway, outer ring raceway curvature center and bearing center consistent.
Fourth, in addition to be able to bear radial load, but also can bear two-way axial load and its combined load. The bearing capacity is larger, and at the same time has better anti-vibration and anti-impact ability.
