Slewing ring ball bearings

Slewing ring ball bearings generally belong in the category of large bearings as they transmit axial and radial forces at the same time. Unlike ball bearings, slewing ring ball bearings are not mounted in a housing or on a shaft. Hence, there are mounting holes in the outer and inner rings to enable optimal power transmission and a quick connection to the relevant and adjacent components. The slewing ring ball bearings are usually assembled on top of each other, but a vertical installation is also possible. In metal slewing ring ball bearings, the rolling elements kept at a distance run along a sealed and lubricated raceway. igus offers customers the option to choose between two different 100% lubrication-free types. In addition to a slewing ring ball bearing that runs on low-maintenance sliding elements, igus offers slewing ring ball bearings supported by ball bearings; no matter whether with outer drive teeth, inner drive teeth or custom-made special parts.

"We were looking for a simple slewing ring bearing that would allow our assembly table to rotate. Using the maintenance-free PRT slewing ring bearings was therefore very helpful, and the cooperation with igus went very well."

"The xiros slewing ring ball bearings impressed us due to their lack of lubrication, smooth running and low weight of the plastic. The individual design options for the products were also very helpful during the development process."
