Since igus® introduced the first openable and (two-part) e-tubes in the mid-1980s, many additional parts and improvements have been added to the programme. Energy tubes can be used in areas with hot chips, dirt and dust caused by woodworking, steel mills, pulp, textiles, agriculture, coal mines and many other unfavourable environmental conditions. Opt for the cost-effective, alternative R100 series for low and medium speed applications.
