EWA14 Series Slewing Drive

ewa14 series slewing drive

Slewing drives work well in applications requiring high torque at low speeds due to their zero-backlash and smooth component operation. They offer superior precision in positioning accuracy and rotational movement. These mechanical devices are ideal for cranes, satellites, radar trackers, oil tool equipment, and various fields that rely on similar functions. They are made of phosphor bronze and steel or materials with associated wear and deformation properties. Rotary drives have housings that protect them from environmental elements, including dirt, dust, and water.

Slewing drives are gearboxes capable of handling radial and axial loads and delivering high rotational torque. These mechanisms produce rotational motion along a single axis or multiple combined axes. Finished gearboxes are assembled from seals, bearings, housings, gearing, motors, and other manufactured components.
