Spherical Roller Bearing
Spherical roller bearings offer a unique combination of high load capacity, high tolerance to shock loads, and self-aligning ability, but they are speed limited. The surface finish of the tracks and rolling elements is critical to the running performance and noise characteristics of these bearings. Spherical bearings are used in vibrators, shakers, conveyors, speed reducers, transmissions, and other heavy machinery. Although the majority of spherical bearings are made to ABEC-1 tolerances, high-precision grades are available.
