RX e-tubes - Novel and extremely chip-proof

The problem solver for energy supply systems in the chip area - available in 4 sizes. Chips and dirt can significantly shorten the service life of cables and hoses. With the RX system, igus® offers an extremely tight, but yet very easy-to-open polymer e-tube.

Openable along the outer radius

Round contour prevents swarf accumulation

Injection-moulded seal between links

No holes, gaps or undercuts

The RX40 series has been IP40 tested (TÜV Saarland)

Interior separation and support tray available

Covered pin/bore connection and stop-dogs

"RBR"version with Reverse Bend Radius available

RX energy tube

Typical industries

  • Machine tools
  • All applications directly exposed to chips and swarf
  • Applications in dusty and dirty environments

Application examples

Applications in various industrial sectors.

RX energy tube

Series RX - new chip-proof design, small pitch, removable cover


Chip-proof design without undercuts or edges


Eccentric locking


Material igumid G


Rounded shape


Covered pin/hole connection

Submersion test in water - Various tube types were submerged under water. The new RX tube needs over 30 seconds until it is filled up, thus proving its high leak tightness
Y = time in seconds
