Double Row Eight Point Contact Ball Slewing Ring

The double row eight point contact ball slewing ring is make up of dual rows of the same sized steel balls and each of the balls is segregated from another one by a spacer. The spacer fixed on the raceway not only can separate the adjacent balls, but also used as a holder of the balls. The internal and external rings are one integral whole and the balls are stuffed in through a hole available for blocking.

Our double row eight point contact ball slewing ring has large radial and axial dimension and firmed mechanical structure. It is an ideal mechanical component of the construction machinery which is in need of heavy load but limited radial size such as tower crane and vehicle crane.

Our product with elliptic raceway is an innovation of slewing ring production industry and receive national patent awards. The ring equipped with the elliptic raceway has 30% more bearing capability and double service life. Its high bearing capability determines that the bearing with elliptic raceway will finally replace the roller slewing ring. The application of elliptic raceway also reduce the purchase cost .

  • Elliptical Raceway Slewing RingAdjusting the levelness of the slewing bearing is critical to minimize tilting moment loads, most notably, when the slewing ring is to be installed on a ladder truck. This self-leveling slewing bearing comes with a leveling instrument that facilitates the adjustment of levelness.
  • Single Row Ball Slewing RingThe single row four point contact ball slewing ring consists of two rings. It has tightened mechanical structure and low weight. Its rolling element is a row of steel balls which connect the elliptic raceway with four points. Therefore, our single row ball slewing ring can bear axial, radial and turnover moment simultaneously...
