Spherical roller bearings are designed with double-row raceway inner ring, spherical raceway outer ring and the convex symmetrical rollers. With the same center as the bearings, the spherically formed outer ring raceway can make self alignment, which can adapt the deflection between axis and housing bore.

 

This kind of bearings can take great radial load, suitable for heavy machines used in paper-making, mining, vibration sieve, rolling mill and so on.
