Spherical roller bearing - Wikiped

A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers.

Development of Super-low Friction Torque Technology for .

Energy Efficiency by Using Innovative Bearing Solutio

internal bearing geometry—as well as of the tribological conditions of relevant friction partners (e.g., roller face versus rib)—plays a key role. Examples used here are low-friction, tapered-roller and deep-groove ball bearings. The third approach facilitates higher efficiency through downsizing. For example, the load-rating capacity of the
