Rotary bearing for welding positioners

A welding positioner is a device that rotates 360°, allowing the welder to remain stationary while consistently working on a flat, accessible surface. It is particularly useful when handling complex-shaped components, such as tubular pipelines or cylindrical structures. By rotating the workpiece instead of the operator, worker fatigue is reduced, productivity increases, and weld consistency improves. Overhead and vertical passes are eliminated, simplifying the process. Most welding positioners use compact, precision slewing bearings that serve both for steering adjustment and load support. The reliability and accuracy of the slewing bearing are critical to the performance and longevity of the entire positioning system.
