The dual axis slewing drive is a highly integrated unit designed for both vertical and horizontal mounting applications. It combines a slewing bearing, worm gear transmission, motor and sealing system into a compact and robust structure.
By using two-axis slewing drive (azimuth and elevation), the solar trackers’ energy yield can be maximized up to 40% more. It can keep solar panels perpendicular to sunlight throughout the day and seasons. It offers greater flexibility in equipment design while reducing overall system cost.


Key Features

  • Use a toroidal double-envelope worm gear to achieve multi-tooth contact and double-contact line contact improves load-bearing capacity.
  • Suitable for applications requiring both azimuth and elevation tracking
  • Simplify system structure, save installation space and reduce installation costs
  • Provide reliable self-locking for its worm gear structure under most working conditions, enhancing operational safety.
  • Multiple sealing protections ensure stable performance in outdoor, dusty, and harsh environments.


Typical Applications

  • Dual axis solar tracking systems
  • Radar, antenna, and surveillance systems


Optional Configurations

  • Offer various gear ratios and output torque ranges
  • Available with electric motors, hydraulic motors, stepper motors or servo systems to meet different control requirements.
  • Available with encoders, limit switches, corrosion-resistant coating, and customized solutions.
