Introduction of bearing 22340mb
Self-aligning roller bearing is designed to adapt to the circumstance of heavy load. It has
two rows of symmetric spherical rollers.The rollers may freely adjust position in the outer
spherical raceway,which may compensate the shaft deformation and non-alignment error
of bearing seat.
The quantity,length and diameter of roller in self-aligning roller bearing are the max.value
that the structure allows.The close contact between the roller and raceway ensures the
uniform stress distribution and enables the high bearing capacity of bearing.
printing presses, paper mills or coaters in high precision execution
very arduous operating conditions, e. g.continuous casters
high temperature applications
mounting with loose fit on roll necks
Spherical roller bearings with two rollers, mainly bear radial load, but also can withstand
axial load in either direction. A high radial load capacity, especially suitable for heavy loads
or vibration, but can not bear the pure axial load. This kind of bearing outer ring raceway
is spherical shape, so the good performance of its self-aligning, can compensate concentricity
There are two symmetrical spherical roller, there is a common spherical outer ring raceway,
the bearing inner ring with two axis tilt
Angle of raceway, aligning with good performance, when the axis force bent or install a
different heart is still bearing the normal use, transfer concentric with the bearing size
range varies,generally aligning allowed 1 to 2.5 degree angle load bearing capacity of the larger
type, in addition to radial loads but also under way outside the role of bearing axial load, with
good impact resistance, in general, self-aligning roller bearings allowed working speed than the
