Self-aligning roller bearing is one of the most able to bear the heavy load bearing. Such bearings have two rows of spherical rollers (symmetric shape and non-symmetrical shape), the outer ring raceway is spherical shape, with self-aligning properties. Such bearings can bear radial load and bi-directional load, in particular, large radial load capacity.
Type of bearings for heavy load and shock load to bear, is widely used in metallurgy, rolling mills, mining, petroleum, paper, cement, pressed sugar and other industries.
