• Eight-point contact same path slewing bearings, also called double row same path ball slewing bearings, have good rotational speed, flexibility, light weight, etc. They have anti-fatigue design, high load capacity and long life.
  • Double row same path ball slewing bearings are mainly used in wind turbine equipment and concrete transportation pump truck. In wind turbine equipment, double-row same path ball slewing bearings are installed at the root of the propeller to act as a side propeller, with zero or negative bearing clearance requirements and high starting friction torque and high slewing accuracy. In terms of its own characteristics, double row same path ball slewing bearings have a compact structure, which can effectively save the center diameter of the inner ring and outer ring mounting holes, and at the same time improve the load carrying capacity.
  • We all know that automobile cranes, excavators, truck cranes, fixed cranes, lifting bearings, marine equipment and construction cranes need a certain load-bearing capacity, and double-row same path ball slewing bearings can be a good solution to the relationship between the speed and load-bearing bearing diameter is basically in the range of 500-2000mm, between 2100-3500mm, the load-bearing capacity in the range of 150T or less, beyond the range. It is recommended to use Three-row roller bearings.
