Thrust (axial) spherical roller bearings are mainly designed to accommodate the axial load, but can accommodate some radial load too. As the rolling elements and the raceway of the loose ring are sphered, the bearing is self-aligning, permitting the misalignment angle up to 3°, which makes the bearing insensitive to the shaft deflection and to the mistakes of shaft centering during its mounting relatively to the housing. The design of thrust (axial) spherical roller bearings is split, which simplifies their installation. Due to the influence of centrifugal and gyroscopic forces these bearings must constantly be subjected to minimum load. Thrust (axial) spherical roller bearings are fitted with pressed steel or machined brass cages.
