Slewing Drive

Slewing drive—also known as slewing reducer or turntable reducer—is a fully rotatable reduction transmission mechanism that integrates a drive power source.

It utilizes a slewing bearing as both the driven component and the structural mounting point by attaching the driving element, power source, and housing to one race (inner or outer) while using the other as the driven component and mounting base, the unit integrates the functions of rotation, speed reduction, and driving.

ZMS can supply gear-type and worm-gear-type slewing drives including series SE/PE Series, WEA Series, WE Series, Double-row ball slewing drives, Dual-worm slewing drives. We can also custom made slewing drives as customer requirements.

They are widely used on construction machinery, solar tracking systems, industrial robots, and wind power equipment, meeting requirements for high torque transmission and compact design.

Highly integrated

Slewing drive is a highly integrated reduction mechanism capable of full-circle rotation. Due to the significant size difference between the driving and driven components, it facilitates the achievement of high gear ratios.

Reverse self-locking

Worm gear drives possess the characteristic of reverse self-locking; that is, the worm can drive the worm gear, but the worm gear cannot drive the worm.

Easy install

Pre-assembled and lubricated at the factory. Simply bolt it down, connect the motor, and operate.

Advantages

ZMS supply key components utilize high-performance materials and specialized heat treatment processes, ensuring exceptional stability and longevity regarding both service life and precision.capable of ensuring sufficient output torque and precise drive positioning in wind speeds of Force 7.

The surface is protected using high-temperature electrostatic spraying technology, offering excellent corrosion resistance and enabling reliable operation in harsh environments.

The corrosion protection rating meets or exceeds C5, and it withstands 1,400 hours in the neutral salt spray test.

Ensures excellent weather resistance and sealing performance, with an ingress protection rating of up to IP65, enabling the product to withstand harsh environmental and climatic conditions such as rain, snow, dust, strong winds, and extreme temperatures.

It utilizes high-performance internal grease, extending the maintenance interval to over five years; with the application of specialized grease, it can achieve a maintenance-free status.

Applications

Wind turbines and solar trackers are the primary application areas for slewing drives.Currently, over 60% of manufactured units are used in these two sectors. Thanks to their compact structure and short drive train, slewing drives can readily achieve high precision and facilitate digital control.

They are also widely applied in the field of industrial robots.

Furthermore, slewing drives are extensively used in construction machinery—such as cranes and excavators—due to their high torque, smooth rotation, and reliable load-handling capabilities.

Additionally, there is demand for their application in sectors such as new-energy construction machinery, industrial automation, rail transportation, and aerospace.
