T1120FS-T1120S bearings ( 279.4 mm x 603.25 mm x 161.925 mm) have the advantages of Withstanding extremely large and heavy unidirectional axial thrust, and are therefore widely used in the crane hooks, oil well swivels, pulp refiners.

The T1120FS-T1120S Thrust tapered roller bearings mainly consist of a shaft ring, a housing ring, tapered rollers, and a cage. The raceways of the shaft ring and housing ring have a conical surface structure, and the rollers make line contact with the raceways. The cage is typically made of machined brass or stamped steel to ensure proper roller guidance.
Thrust tapered roller bearings can withstand enormous unidirectional axial loads and also possess a certain radial load-bearing capacity, far exceeding that of thrust ball bearings. They offer high rigidity, strong impact resistance, and precise axial positioning and preload can be achieved through the tapered roller structure.
