148TTSF926OO487 Screwdown Bearings, Heavy-duty Thrust Tapered Roller Bearing With Two Tapered Raceways
The 148TTSF926OO487 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 148TTSF926OO487 bearing is a thrust tapered roller bearing, screwdown bearings, Heavy-duty thrust tapered roller bearing with two tapered raceways with an an outer diameter of 377.825 mm, a width of 129.007 mm. It typically uses PN (ABEC-1) grade precision tolerances and bearing steel rings, bearing steel rolling mlement. its static axial rated load is approximately 17434139 N. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
148TTSF926OO487 bearings (377.825 mm x 129.007 mm) have the advantages of Withstanding extremely large and heavy unidirectional axial thrust, and are therefore widely used in the Heavy machinery, rolling mills, ship propulsion systems, cranes, and oil drilling rigs.

The 148TTSF926OO487 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.
