Theplastic energy tube RX from igus is almost one hundred per cent airtight (2.7 g chips after 251,900 cycles). The rounded design without undercut or edges and the smoothly curved outer contour allows chips - from coarse to tiny particles - to simply slide off. In addition, the connection elements and fittings are concealed, so that chips cannot be caught on these either. Alongside the three design sizes with an inner height of 52, 62 or 73 mm, there is now a new design size available with a maximum inner height of only 42 mm. The new size is available with the option of a high-temperature variant, resistant to hot chips up to 850°C, and as a variant with reverse bending radius (RBR). Dust, dirt, oil, aggressive environment conditions, humidity and heat have no affect whatsoever on the sturdy energy chains.
