EWA12 Series Slewing Drive
The slewing drive is a gearbox that can safely hold radial and axial loads and transmit torque for rotating. The rotation can be on a single axis or multiple axes together. Slewing drives are made by manufacturing gearing, bearings, seals, housing, motor, and other auxiliary components and assembling them into a finished gearbox. The slewing drive uses precision kinematics to provide a large proportion of single-stage gearing. Bearings and gears are made into a small, self-contained, ready-to-install case to optimize weight and performance.

These highly adaptable products also feature robust shock resistance, long life performance, smooth rotation, bearing protection, and sealed drive options. As an experienced slew drive manufacturer, we can provide high-quality slew drives.
Types of Slewing Drives
Slewing drives offer various sizes, capacities, and mounting features to fulfill many functions. Standard models have dual-axis drives turning simultaneously or two drives positioned on the same axis. The two-drive setup allows two worm threads to drive a ring gear along one axis.
Emerging technologies led to an increase in the popularity of the hourglass design in slew drive manufacturing. The new design offers superior performance by employing multiple gear teeth simultaneously. Slewing drives, designed to handle heavier loads, utilize double-row slew bearings instead of single-row bearings.
With a specialized application in solar tracking systems, slewing drives assist in generating a higher solar power output. This is achieved by facilitating equipment mobility with a focus on the sun. Custom solutions are made for applications requiring exceptional load capacity utilizing dynamic and static torque.

Typical Case of Slewing Drive
Slew drives are used in industries across the globe. They are used in a variety of applications when it is desired to magnify the power of a motor into a controlled, high torqued output. Because of their ability to withstand (and hold) high loads and deliver high rotational torque, slew drives are used in a variety of industries, such as the following:
(1) Robotics: Slew drives allow the controlled movements required in the automation industry.
(2) Cranes and Lifts: Because of their ability to hold high loads, slew drives are commonplace in cranes and lifts.
(3) Earth Moving and Heavy Machinery: The high torque output and controlled movements possible with slew drives make them ideal for earth-moving equipment.
(4) Wind Energy: Due to their ability to hold high loads, slew drives are commonplace in wind turbines, allowing a turbine's controlled turn to face the oncoming wind.
