Spherical roller bearings are mainly used to bear radial load, but also can withstand a certain amount of axial load, but generally can not bear the pure axial load. This kind of bearing outer ring raceway is spherical shape, aligning performance residence there, when the shaft by the legislature leaving the inner bend or tilt relative to the centerline of the centerline of the outer ring tilt does not exceed 0.5 ° ~ 2 °, the bearing can still be normal work. Principles and characteristics of its structure and the same self-aligning ball bearings, the only difference is that the rolling body is spherical roller, due to the different rolling element, and thus the carrying capacity of its large, widely used in mining and heavy machinery. Axial clearance range Bearing such limit the axial displacement of shaft or housing in the bearing. Spherical roller bearings and self-aligning ball bearings, in conformity with the capacity and speed limits permit, you can substitute another.
