NTN 29326 Round Bore Self-Aligning Spherical Roller Thrust Bearing, 130 mm Dia Bore, 225 mm OD, 1 Row, 58 mm W, 2100000 N Load

Just like spherical roller bearings, the center of the spherical surface for spherical roller thrust bearings is the point where the raceway surface of the housing raceway washer meets the center axis of the bearing. Since spherical roller thrust bearings incorporate barrel-shaped rollers as rolling elements, they also have self-aligning properties. Under normal load conditions, the allowable misalignment is 1 deg to 2 deg, although this will vary depending upon the bearing's dimension series. These bearings use machined copper alloy cages and a guide sleeve is attached to the inner ring to guide the cage. The axial load capacity of these bearings is high, and a certain amount of radial load can also be accommodated when the ring is in an axially loaded state.
