♥ Main application -- spherical roller bearings is mainly used for
medium and large motors, generators, internal combustion engines,
gas turbines, machine tool spindles, deceleration devices, and
material handling machinery and various types of industrial
machinery.

cases
♥ Production range -- standard and non-standard
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
error.
There are two symmetrical spherical rollers, 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 low.

Self-aligning Spherical roller bearing Application:
1. printing presses, paper mills or coaters in high precision
execution
2. very arduous operating conditions, e. g.continuous casters
3. high-temperature applications
4. mounting with a loose fit on roll necks
5. railway vehicles
