The double-row equal-diameter four-point contact ball slewing bearing ingeniously combines the double-row ball layout with the four-point contact principle, achieving an excellent balance among anti-overturning moment capacity, structural compactness, and comprehensive load-bearing performance.

Its structural feature lies in that the rolling elements (steel balls) are in four-point contact with the raceways, and all rolling elements maintain the same diameter. This design enables the bearing to simultaneously withstand multi-directional loads such as axial loads, radial loads and overturning moments. It boasts high rigidity and stability, making it suitable for various heavy-duty application scenarios.

The double-row ball design increases the number of contact points, which can not only distribute the load and reduce the pressure on individual steel balls, thereby extending the service life of the bearing, but also endow the bearing with excellent performance under complex load conditions thanks to its four-point contact structure. It is particularly applicable to equipment that needs to bear multi-directional loads at the same time. In addition, this structure can effectively reduce the occurrence of rolling element slippage, further enhancing the rigidity and operational stability of the bearing.
