29480M spherical roller thrust bearings for tower cranes-THB Bearings

THB spherical roller thrust bearings have specially designed raceways and accommodate a large number of asymmetrical rollers. The rollers have an optimum conformity with the washer raceways to optimize load distribution along the roller length. Therefore, they can accommodate relatively high speeds, heavy axial loads in one direction and heavy radial loads. The load is transmitted between the raceways at an angle to the bearing axis. Spherical roller thrust bearings are self-aligning and insensitive to static misalignment of the shaft relative to the housing.

Application: tower crane, oil wel rig, iron-steel machinery, hydroelectric generator, vertical type motor, ship propeller shaft, extruding machine, etc.
