Product Description
DRE slewing drives are powered with hourglass worm technology for maximum gear torque and the smoothest rotation. Typical slew drive applications include solar industry, truck cranes, man lifts, utility equipment, hydraulic attachments, oil tool equipment, marine cranes, tire handlers, digger derricks and automotive lifts, but the slew drives are used in many other applications requiring load holding and rotational capability. We offer different slew drive models with different moment load capacities.  

Solar Tracker Slew Drive
The standard slew drives are fitted with an open housing and single self locking hourglass worm shaft. Once the power source input is returned to neutral, the worm shaft will lock the load into position without requiring any external braking device.
 
The slew drive can be with worm gear and helical gear. And also for the inside slewing ring, it can be single-row ball slewing ring, and also can be double-row ball slewing ring. The one with double-row can take much more load. It can be chosen depended on your application.


Below you can find the reference number of slew drive. For the one we do not list as below, please contact with us.
 

Slew Drive with Helical Gear (SE Enclosed Slew Drives)

SE Enclosed Slew Drives help power movement across industries and are perfect for situations requiring both load-holding and rotational torque from the same gearbox.

Typical applications include solar trackers, wind turbines, satellite and radar dishes, truck cranes, man lifts, utility equipment, hydraulic equipment attachments, oil tool equipment, tire handlers, digger derricks, and automotive lifts.

Dual axis slew drive (SDE type) - Solar tracker slew drive

The SDE series designing is absorbs the advantages of VE and SE. The Azimuth and Elevation 3D direction rotating at the same time.
The most common slewing drive application for the dual-axis slewing drives are dual-axis solar trackers, such as heliostats and concentrated photovoltaics (CPV), and satellite or radar dishes. Other applications include automotive lifts, robotic arm positioners, and stage equipment.

Slew Drive with Worm Gear (WE type)

WE series slewing drive is similar to the SE, but the difference is designed with curved tooth slewing ring, the output torque is increased, with the smooth running of a superior anti-sandstorm, field use, etc.

The WE series is a good choice when you are in the Wild harsh working conditions and need anti-glued more stronger.

Slewing drive for modular vehicles (HSE type)

The HSE type slewing drive is mainly designed for the hydraulic module car. Since the slewing bearing is the main part, this system has stronger dynamic axial load and tilting moment.

Slew Drive with Open Housing (S type)

The S open hourglass is excellent for low-cost manufacturing equipment that requires daily maintenance and checks or doesn't need to be covered.

Typical uses for this S open-housing slewing drive include many mobile applications such as man-lifts, utility equipment, turntable applications, digger derricks, and steering applications.

Slew Drive with Two Worms (SE-2 type)

SE-2 Series slewing drives are combined by VE Housing, slewing ring, two hourglass worm and some Matching parts, it achieved 2 times of tooth contacting. In the same volume and installation space, it improved nearly double output torque, greatly improving the product's performance.
