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 work loads or vibration, but can not afford pure axial load. This kind of dental bearing outer ring raceway is spherical shape, so its good self-aligning, can compensate concentricity error.
There are two symmetrical spherical roller, spherical ball bearings there is a common spherical outer ring raceway, and the bearing inner ring with two axis tilt angle of the raceway, aligning with good performance, when the axial force bent or install a different heart while still bearing the normal use, transfer concentric with the bearing size range varies, generally allowable aligning angle is 1 to 2.5 degrees, the larger the load bearing capacity of this type, in addition to radial loads outer bearing can withstand double-acting axial load, has good impact resistance, in general, spherical roller bearings allowed operating speed is low.
