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.
