Description:
These bearings have barrel-shaped rollers between the inner ring,
which has two raceways, and the outer ring which has one spherical
raceway. Since the center of curvature of the outer ring raceway
surface coincides with the bearing axis, they are self-aligning in
a manner similar to that of self-aligning ball bearings. Therefore,
if there is deflection of the shaft or housing or misalignment of
their axes, it is automatically corrected so excessive force is not
applied to the bearings.
Spherical roller bearings can take, not only heavy radial loads,
but also some axial loads in either direction. They have excellent
radial load-carrying capacity and are suitable for use where there
are heavy or impact loads.
