Spherical roller bearings with two rollers, mainly bear radial load but also can withstand axial load in either direction. A high radial load capacity, especially suitable for heavy loads or vibration, but can not bear the pure axial load. This kind of bearing outer ring raceway is spherical shape, so the good performance of its self-aligning can compensate concentricity error.

There are two symmetrical spherical rollers, there is a common spherical outer ring raceway, the bearing inner ring with two axis tilt

Angle of raceway, aligning with good performance when the axis force bent or install a different heart is still bearing the normal use, transfer concentric with the bearing size range varies, generally aligning allowed 1 to 2.5-degree angle load-bearing capacity of the larger type, in addition to radial loads but also under way outside the role of bearing axial load, with good impact resistance, in general, self-aligning roller bearings allowed working speed than the low.

Self-aligning Spherical roller bearing Application:

1. printing presses, paper mills or coaters in high precision execution

2. very arduous operating conditions, e. g.continuous casters

3. high-temperature applications

4. mounting with a loose fit on roll necks

5. railway vehicles
