QJF1080X1 Four Point Contact Ball Bearing

The QJF1080X1 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 400mm bore diameter, 600mm outside diameter and 90mm width. The optimized raceway geometry allows 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 512 kN and a static load rating of 1083 kN. Equipped with a steel cage, it offers reliable performance with limiting speeds of 700 r/min under grease lubrication and 450 r/min under oil lubrication.

QJF1080X1 four point contact ball bearings are suitable for heavy mining equipment, large gearboxes, industrial machinery 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.
