Detailed description
T1080FA bearings ( 250 mm x 379.949 mm x 100 mm) have the advantages of Composite load, high speed, high rigidity, and are therefore widely used in the rotary tables of oil and gas drilling rigs.

The T1080FA Thrust angular contact ball bearings are mainly composed of precision-ground steel balls, hardened and ground steel raceways, and a brass (or bronze) cage. Their core characteristic is their ability to simultaneously withstand axial thrust loads and a certain amount of radial load, and they also feature low friction, quiet operation, and suitability for high-speed operation.
