Spherical bearings offer an unrivaled combination of high load capacity, high tolerance to shock loads, and self-aligning ability. While they are rugged, spherical bearings are speed limited. Thus, these bearings are used in vibrators, shakers, conveyors, speed reducers, transmissions, and other heavy machinery.
