Slewing Rings

Slewing rings are rolling bearings designed to safely and precisely accommodate axial, radial, and tilting loads. They enable smooth rotational movement between two components and are used wherever high forces need to be reliably transmitted. Typical applications include mechanical and plant engineering, conveyor technology, wind turbines, construction machinery, and many specialized industrial applications.

Thanks to their compact design, slewing rings combine multiple functions in a single component. This simplifies designs, saves installation space, and significantly increases machine efficiency. Depending on the application, various designs are available, including ball rotary joints, roller rotary joints, and cross-roller bearings. Variants with internal gear teeth, external gear teeth, or without gear teeth are also available, allowing the bearings to be optimally integrated into existing drive concepts.

A key advantage of slewing rings is their high load-carrying capacity combined with precise and smooth motion. They are specifically designed for low to medium speeds and operate reliably even under difficult conditions. High-quality sealing systems protect the rolling elements from dirt, dust, and moisture, thereby contributing to a long service life.

Selecting the right slewing rings depends on many factors. In addition to the forces involved, installation space, rotational speed, environmental conditions, and the desired service life also play a key role. Careful design ensures that the bearing solution is optimally tailored to the specific application and functions reliably over the long term.
