Whether in laboratory technology, furniture technology or fitness machines – in applications where precision in the tenth of a millimetre range is sufficient, but very quiet operation is required, linear guide with sliding elements made of plastic are very impressive. In contrast to recirculating ball bearing guides no metallic bodies are rolled here, which causes vibrations and thus increases decibel levels. In the video the motion plastics specialist igus shows the comparison of different drylin guide systems with dimensionally identical alternatives. On average, the linear guides from igus are about 20 decibels quieter. This corresponds roughly to the difference between a running refrigerator (~50 dB) and a vacuum cleaner (~70 dB).
