Spherical Roller Bearings
Spherical roller bearings have a spherical raceway on the outer ring, with the center of the sphere coinciding with the bearing center. The inner ring has two raceways inclined at an angle to the bearing axis, providing excellent self-aligning performance. These bearings are mainly used to support radial loads and can also accommodate axial loads in either direction. They are suitable for heavy-duty machinery used in mining, metallurgy, papermaking, construction and other industries.
