The stage lighting systems used in lighting equipment must be lightweight, and operate quietly and reliably. By using igus® high-performance plastics, spotlights can run lubrication and maintenance-free. Plastic plain bearings and linear guides from igus® allow quiet and smooth movement because they do not use metal balls. Compared to rotating steel ball bearings, the simpler type of movement reduces noise, while saving up to 40% in costs. In addition, energy chains prevent cable failures and extend machine runtimes.
