126TTSV922 Screwdown Bearings, Heavy-duty Thrust Tapered Roller Bearing Having One Flat And One Tapered Raceway
The 126TTSV922 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 126TTSV922 bearing is a thrust tapered roller bearing, screwdown bearings, Heavy-duty thrust tapered roller bearing having one flat and one tapered raceway with an an outer diameter of 320.675 mm, a width of 95.25 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 12535050 N. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
126TTSV922 bearings (320.675 mm x 95.25 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 126TTSV922 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.
