SELF-ALIGNING
BALL BEARINGS
The
outer ring raceway of self-aligning ball bearing forms a
spherical surface whose center is common to the bearing
center. The inner ring of the bearing has two raceways.
The balls, cage and inner ring of these bearing are capable
of a shifting in order to compensate for a certain degree
of missalignment with the outer rings.
As a result the bearing is able to align itself and compensate
for shaft/ housing finishing unevenness, bearing fitting
errors and other sources of missalignment.
However since axial load capacity is limited self-aligning
ball bearing are not uitable for applications with heavy
axial loads.
Furthermore if an adapter is used on the tapered bore of
the inner diameter, installation and disassembly are much
simplier and this reason adapters are often used on equipment
with drive shafts.
All bearing series are equipped with a pressed cage, except
2322S (equipped with a machined cage).
