Slew Drive

A Slew Drive is a type of gearbox that is specifically designed to handle high radial, axial, and moment loads. They are designed to withstand hold loads while also providing high rotational output torque. Slew drives consist of a worm gear mechanism, a metal bearing component, rubber seals, and sturdy housing to prevent environmental factors such as dirt, water, and dust from destroying the working components of the drive. Slew drives operate fundamentally identical to worm gears. As a worm gear rotates, it translates rotational motion along its axis to rotary motion of the axis it is perpendicular to. The driven member (the worm wheel) consequently exhibits a decrease in speed and a proportional increase in torque from the worm gear. The output speed of the worm wheel is dependent upon the ratio of the threads on the worm gear to the number of teeth on the worm wheel.

  • Rated Dynamic Torque Range: From 3000 Nm to 13000 Nm (Based on the yearly torque Histogram, Worm Gear configuration can be changed)

  • Tracker Holding/Non-Back Driving Torque Range: From 12000 Nm to 50,000 Nm

  • High-Performance Worm Gear Pair: 20 years designed for outdoor applications, it ensures exceptional holding torque strength, minimum wear, and durability even under reversible torque conditions.

  • Customized Design for Seamless Integration: The slew drive design can be fully customized to match your tracker interfaces and adapt to your torque tube design, ensuring effortless compatibility with your application.

  • Superior Corrosion Resistance: Equipped with a specially developed coating and paint system, the gearbox is tested to withstand harsh and highly corrosive environments, delivering long-lasting protection in extreme conditions.

  • Built to Endure the Outdoors: Engineered for rugged reliability, the design is maintenance-free and proven to perform in temperatures ranging from -400C to +650C. With advanced IP protection, it stands strong against dust, water, and environmental stress.

  • Rated max dynamic load: for 19,000 cycles 31,000N push/pull, extreme load: 50,000N

  • Static load: max 110,000N quarter extended, 72,000N half extended, 55,000N fully extended

  • Max lateral load of 2500N at eyelet when fully extended
