triflex® R (R for "round") is the third generation 3-axis energy chains from igus®. The multiaxial energy supply system triflex® R has been specially developed for the sophisticated 6-axis robotic applications in harsh industrial environments. Some of the important design features are: Fiber rod option for the partial reinforcement of the triflex® R, approximately ±10° Torsion per chain link, high tensile strength through ball-and-socket joint. In the meantime, the triflex® R product range consists of more than 100 components, so that all requirements of large welding robots up to the small pallet robots can be met. triflex® R has received the iF design award.

Typical industrial sectors and applications:

First choice for industrial robots, machine tools, 6-axle handling equipment, conveyor technology, general mechanical engineering and many more.

Automotive industry

Multidimensionally moveable energy supply systems provide the highest flexibility and the longest holding times in all complex movements, and at the same time are installation friendly.

Clean room technology

The number of freely hanging cables should be bundled together. The specific movements executed by the robot stress the energy cables to a high degree.

Pharmaceutical industry

The task was to design a reliable handling and also update it optically according to the latest technology.
