What is a slewing drive?

A slewing drive, also known as a slewing gear or slewing ring drive, is a compact and versatile mechanism used to provide rotational movement in various applications. It consists of a gearbox, a bearing, and a motor or hydraulic system.

The slewing ring bearing is a large diameter ring with raceways that allow for smooth rotation. It is designed to withstand heavy loads and provide support for the rotating structure. The bearing is typically made of high-strength steel and is capable of handling axial, radial, and moment loads.

The motor or hydraulic system provides the driving force for the slewing drive. It can be an electric motor, hydraulic motor, or even a combination of both, depending on the specific application requirements. The motor or hydraulic system is responsible for generating the necessary torque and controlling the speed and direction of rotation.

Slewing drives are known for their compact design, high efficiency, and ability to handle heavy loads. They offer precise positioning and smooth rotation, making them essential components in various industries. The versatility of slewing drives allows for customization and integration into different types of machinery and equipment, providing reliable and efficient rotational motion solutions.
