Detailed description
D-3327-G bearings ( 550 mm x 760 mm x 230 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 D-3327-G 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.
