22316CA 22316CC 3616 22316E Spherical Roller Bearings

Self-aligning roller bearings are used to bear radial load, and at the same time also can bear a certain amount of axial load, but generally can't bear pure axial load. This kind of bearing's outer ring raceway for spherical shape, former residence have self-aligning properties, when the shaft made by causes the bending or tilted and make the inner ring center line and the center line of the outer relative inclined not more than 0.5 ° ~ 2 °, bearing can still work normally. Its structure principle and characteristic and self-aligning ball bearing the same, the only difference is that rolling body is spherical roller, due to the rolling element is different, so it's bearing capacity is larger, widely used in mine and the heavy machinery. This kind of bearing can limit shaft or shell axial displacement in bearing axial clearance range. Self-aligning roller bearing and self-aligning ball bearing, in accord with capacity and limit speed situations, we can substitute each other.
