Spherical Roller Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection and with relatively heavy radial loads and some axial loads in either direction. They are also extremely resistant to shock loads and their self-aligning feature allows full capacity loading despite shaft deflection. They are very similar in purpose to Self-Aligning Double Row Ball Bearings, except the Spherical Roller Bearings are designed to be more robust by carry heavier loads but at lower maximum speeds. These bearings have barrel-shaped rollers between the inner ring, which has two raceways, and the outer ring which has one spherical raceway. They are self-aligning because the center of curvature of the outer ring raceway surface coincides with the bearing axis.
Spherical roller bearing:
1. Kinds :bore is the taper K ; and vice versa; tank in the out ring W33
2. Dimensions rage: inter diameter 90mm~~outer diameter 920mm
3. Basic types: 21000; 22000; 23000; 24000; and so on.
4. Cage: brass cage or steel cage
5. Application: wheel, large size agriculture machinery, main shaft of machine tool, deceleration device of railway gear box, roll machine and so on
