Spherical Roller Bearings

Spherical Roller Bearings have two rows of symmetrical rollers, a common sphered external ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the external ring raceway is at the bearing axis.
Spherical Roller Bearings are created to operate in applications where extreme misalignment exists whether from mounting or shaft deflection and with relatively heavy radial loads and some axial loads in either direction. They are likewise exceptionally resistant to shock loads and their self-aligning function enables full capacity filling in spite of shaft deflection. They are extremely similar in function to Self-Aligning Double Row Ball Bearings, other than the Spherical Roller Bearings are created to be more robust by bring heavier loads however at lower maximum speeds. These bearings have barrel-shaped rollers in between the inner ring, which has 2 raceways, and the external ring which has one spherical raceway. Due to the fact that the center of curvature of the outer ring raceway surface coincides with the bearing axis, they are self-aligning.
Requirement Spherical Roller Bearings are produced with straight bores; however, tapered bores are available upon demand and may be installed straight on tapered shafts. Pushed steel and machined brass cages are usually used.
The border dimensions of rolling bearings are the dimensions that define their external geometry and have been internationally standardized (ISO 15) and embraced by JIS B 1512 (Boundary Measurements of Rolling Bearings).
