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.

Applications with cobots

Palletising with cobots

TRE.40.058.0.B in conjunction with the UR metal clamps ensure a trouble-free energy supply on the cobot.

Quality control tests with cobots

The cable to the 2D camera and the vacuum hose are safely guided through the TRE.40.058.0.B and attached to the cobot with the UR metal clamps.

LED bulbs production with cobots

The TRE.40.058.0.B in combination with UR metal clamps ensure trouble-free cable guidance on the cobot for LED bulb production in confined spaces

Multi-directional sideloader

This sideloader solves flexible logistics tasks for wooden panels.

Robots in the automotive industry

Energy supply system for robots in car factory: two-thirds fewer failures

Assembly robots in the 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.

Multi-axis robots

Maintenance free with cables and multi-dimensional energy chains.

Satellite salvage service

An increasing amount of space junk, in other words no longer required or defect parts from space missions orbiting the earth, is also threatening current missions.

Household appliances production

Just 24 hours passed between order, delivery and installation. The entire system functions without any problem from the first day on.

Safe, flexible cable guidance for KUKA articulated arm robots in aircraft construction

An Airbus subsidiary specialised in CFRP processing in aircraft construction uses triflex R and E4/4 plastic energy chains for cable guidance.

Handling system

Robotic handling system for circuit boards. Flexible energy supply system in use in clean room technology.

Automatic screwdriver system

A faultless supply of screws is guaranteed by the bend protection of the triflex® R system.

Dummy robot

A very high acceleration provided an enormouschallenge for the design engineers of this robot.

Cable guide on the robot

Prior to the use of the e-chain®, the cables were fastened with cable ties. That frequently led to entangled cables and the corkscrew effect, which lets the cables become susceptible to core ruptures.

Cable guide on the industrial robot

With this industrial robot, a fixed pipe between the 3rd and 6th axis was replaced with a three-dimensional triflex® R energy chain.

Photovoltaic tracking system

Automatically aligning the photovoltaic tracking systems to the position of the sun with the aid of lubricant-free plastic plain bearings produces a particularly high efficiency.


This laser welding robot works extremely fast. Here, a very flexible and, above all, fail-safe energy supply system is required.

Spot welding robot in vehicle construction

The downtimes have been drastically reduced through the use of an igus® solution for this robot in automotive construction, too.
