triflex® R retraction systems TRC TRE TRCF

For supplying energy to articulated robots – Prevents formation of loops

The global growth in automation for industrial production is leading to more and more complex robotic applications. Target cycle times are getting shorter and downtime must also be reduced. To provide reliable protection against premature system failure and downtime, we recommend using a triflex® R e-chain®, especially to bridge the last three rotating axes. The dynamic change in length that´results from the robot's movement is compensated by our triflex® R retraction systems. This constantly guides the igus® e-chain® in a controlled way to prevent the formation of loops in the robot's working area.
