Description of spherical roller bearing
Self-aligning roller bearing is designed to adapt to the circumstance of heavy load. It has two rows of symmetric spherical rollers.The rollers may freely adjust position in the outer spherical raceway,which may compensate the shaft deformation and non-alignment error of bearing seat. The quantity,length and diameter of roller in self-aligning roller bearing are the max.value that the structure allows.The close contact between the roller and raceway ensures the uniform stress distribution and enables the high bearing capacity of bearing.
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.
Spherical roller bearings have double-row rollers, the outer ring
has a common spherical raceway, and the inner ring has two raceways
that are inclined at 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 the angle of the shaft and the
bearing box seat on the error or shaft bending. It is suitable for
the occasions where the installation error or the shaft deflection
causes the angle error. In addition to being able to withstand
radial loads, the bearing can also withstand bidirectional axial
loads.
