E2 R100 - Two-piece e-tube - Chip protection - Swivel-on lid

Since igus introduced the first openable (two-part) e-tubes in the middle of the 1980s, the product range has been supplemented with many additional parts and improvements. Energy tubes can be used in areas where there are hot chips, dirt and dust produced by woodworking, steelworks, pulp production, textile manufacture, in agriculture, coal stations and many other unfavourable ambient conditions. Decide in favour of the cost-effective alternative R100 series for applications involving slow and medium speeds.
