NP552714 Thrust Tapered Roller Bearings
The NP552714 Thrust tapered roller bearings are suitable for heavy-duty, high-rigidity axial load applications. Classic applications include crane slewing mechanisms, oil drilling rig rotary tables, rolling mill pressing mechanisms, heavy machine tool spindles, ship propeller thrust shafts, and the axial positioning ends of large gearboxes.
The NP552714 bearing is a Thrust Tapered Roller Bearings with an inner diameter of 1549.999 mm , an outer diameter of 105 mm, a width of 60 mm. It typically uses PN (ABEC-1) grade precision tolerances and bearing steel rings, bearing steel rolling mlement. Its dynamic axial rated load is approximately 1600000 N, its static axial rated load is approximately 59400000 N. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
NP552714 bearings ( 1549.999 mm x 105 mm x 60 mm) have the advantages of Withstanding extremely large and heavy unidirectional axial thrust, and are therefore widely used in the heavily loaded extruders, cone crushers.

The NP552714 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.
