Slew Drives, commonly referred to as a Slewing Gear or Slew Bearings, is a complete, ready to install system that consists of a ball or roller slewing ring bearing, drive train, and completely enclosed housing. It can be customized with hydraulic or electric motors, brakes, planetary gearboxes, corrosion protection, as well as many other options.
Coresun@ Slew Drives decrease costs by replacing complex in-house systems in machines that rotate heavy loads and require functionality and innovation. Each has an unlimited slewing angle and range, move smoothly and jolt-free, no slip-stick effect, and provide the most efficient transmission of high power and torque possible. Our Slew Drives are entirely enclosed and sealed housing withstands harsh environments and increases safety.
As a ready-for-installation system module, they replace countless individual parts. Slew drives are utilized for aerial platforms, defense technology, public transportation, forestry machine sectors, solar trackers, and many more.
