The P-1739-C 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 P-1739-C bearing is a Heavy-duty thrust tapered roller bearing with an inner diameter of 304.8 mm , an outer diameter of 609.6 mm, a width of 215.9 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 2604048 N, its static axial rated load is approximately 31096738 N. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The P-1739-C 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.
