QJF1034X3 Four Point Contact Ball Bearing

The QJF1034X3 Four Point Contact Ball Bearing is designed for applications requiring support of combined radial and axial loads in both directions. Its four-point contact design enables a single bearing to accommodate bidirectional axial loads while providing high rigidity and precise positioning.

This bearing features a 170mm bore diameter, 279.5mm outside diameter and 46mm width. The optimized raceway geometry ensures efficient load distribution between the balls and raceways, reducing wear and improving service life under demanding operating conditions.

The bearing provides a dynamic load rating of 388 kN and a static load rating of 1200 kN. Equipped with a steel cage, it offers reliable performance with limiting speeds of 1500 r/min under grease lubrication and 198 r/min under oil lubrication.

QJF1034X3 four point contact ball bearings are suitable for precision machine tools, industrial gearboxes, heavy equipment and other applications requiring compact design, high axial load capacity and dependable long-term operation. Customized bearing solutions are available according to specific application requirements.
