QJ1068X3 Four Point Contact Ball Bearing

The QJ1068X3 Four Point Contact Ball Bearing is designed for industrial applications requiring support of combined radial and axial loads in both directions. Its four-point contact design allows a single bearing to accommodate bidirectional axial loads while providing high rigidity and precise positioning.

This bearing features a 340mm bore diameter, 500mm outside diameter and 80mm width. The optimized raceway geometry provides efficient load distribution between the balls and raceways, helping reduce wear and improve service life under demanding operating conditions.

The bearing provides a dynamic load rating of 404 kN and a static load rating of 705 kN. Equipped with a steel cage, it offers reliable performance with limiting speeds of 800 r/min under grease lubrication and 380 r/min under oil lubrication.

QJ1068X3 four point contact ball bearings are suitable for textile machinery, industrial transmission systems, 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.
