Product Details

Normally we have hydraulic motors and electric motors for the slew drives, details data as below:

The slewing drive uses standard worm technology in which the worm on the horizontal shaft acts as a gear drive. Rotation of the horizontal screw causes the gear to rotate about an axis that is perpendicular to the axis of the screw. This combination reduces the speed of the driven member and also doubles its torque; as the speed decreases, it increases proportionally. The speed of the shaft is proportional to the number of threads in the worm gear in the number of worm gears or gears.


As technology advances, more rotary drives are using hourglass worm technology, where the shape of the worm can engage more teeth in the gear. This increased tooth engagement results in higher strength, efficiency and durability.

Due to their multiple uses, rotary drives are available in a variety of sizes, performance ranges and mounting features. These drives are ideal for applications that require load holding and rotational torque from the same gearbox. They can also be made by rotating two axes (simultaneously rotating the shaft) or by using a double drive on the same shaft (two worm threads drive the same ring gear on one shaft).
