A self-aligning ball bearing is a bearing equipped with spherical
balls between the inner ring of two raceways and the outer ring
whose raceways are spherical.
The curvature center of the outer ring raceway surface is
consistent with the bearing center, so it has the same centering
function as the self-aligning ball bearing. When the shaft or
housing is deflected, it can be adjusted automatically without
increasing the bearing burden. Spherical roller bearings can bear
radial load and axial load in two directions. Large radial load
capacity, suitable for heavy load and shock load. The inner
diameter of the inner ring is a bearing with a tapered bore, which
can be directly installed. Or use an adapter sleeve or a
disassembly tube to install it on the cylindrical shaft. The cage
uses a steel stamping cage, a polyamide forming cage and a copper
alloy car cage.
Self-aligning ball bearings have two structures: cylindrical bore
and tapered bore, and the cage is made of steel plate, synthetic
resin, etc. Its characteristic is that the raceway of the outer
ring is spherical, with self-aligning property, which can
compensate the errors caused by the misalignment and shaft
deflection caused by the self-aligning ball bearing, but the
relative inclination of the inner and outer rings shall not exceed
3 degrees.
It can withstand large radial loads and at the same time can
withstand certain axial loads. The outer ring raceway of this type
of bearing is spherical, so it has self-aligning performance. When
the shaft is bent or tilted so that the center line of the inner
ring and the center line of the outer ring are not more than
1°~2.5°, the bearing can still work .
The inner hole of the self-aligning ball bearing has two types:
cylindrical and conical. The taper of the conical inner hole is
1:12 or 1:30. In order to enhance the lubrication performance of
the bearing, an annular oil groove and three oil holes are machined
on the outer ring of the bearing.
