Spherical
roller bearings have two rows of spherical rollers, the outer
ring has a common concave spherical raceway, the inner ring has
two concave raceways that are inclined at an angle to the bearing
axis, and the curvature center of the outer ring raceway is the
same as the bearing center. Spherical roller bearings are
self-aligning, not affected by shaft and bearing box misalignment
or shaft deformation deflection, and can compensate for the
resulting concentricity error. In addition to bearing radial
load, this type of bearing can also withstand two-way axial load
and its combined load, with a larger load capacity, while having
a better anti-vibration, and anti-impact ability. Spherical
roller bearings are mainly used in steel, mining, paper, ships,
textile machinery, coal mills, electric power, and other
industries in a variety of mechanical equipment, and are the most
widely used in the machinery industry in a class of
bearings.
