BearingsSelf aligning ball bearing is a kind of bearing with
spherical ball between the inner ring of two raceways and the outer
ring with spherical raceway. The curvature center of the outer ring
raceway surface is consistent with the bearing center, so it has
the same self-aligning function as the automatic self-aligning ball
bearing. When the shaft and shell are flexed, it can be adjusted
automatically without increasing the bearing load. Self aligning
roller bearing can bear radial load and axial load in two
directions. Radial load capacity, suitable for heavy load, shock
load. The inner diameter of the inner ring is a taper hole bearing,
which can be directly installed. Or it can be installed on the
cylindrical shaft by using the fastening sleeve and the dismounting
cylinder. The cages are made of steel stamping cages, polyamide
forming cages and copper alloy car cages. The self-aligning ball
bearing has cylindrical hole and conical hole. The cage is made of
steel plate and synthetic resin. Its feature is that the outer ring
raceway is spherical, with automatic self-aligning, which can
compensate the error of self-aligning ball bearing caused by
different centrality and shaft deflection, but the relative
inclination of the inner and outer rings shall not exceed 3
degrees. It can bear large radial load and certain axial load. The
outer ring raceway of this kind of bearing is spherical, so it has
self-aligning performance. When the shaft is bent or tilted, the
relative inclination between the inner ring center line and the
outer ring center line is not more than 1 ° to 2.5 °, the bearing
can still work. There are two kinds of bore in self-aligning ball
bearings: cylindrical bore and conical bore. The taper of 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. Product
