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 increasingly complex applications, particularly when using industrial robots. Even with greater integration and new production processes, target cycle times have to be kept as short as possible and downtime reduced as much as possible. To provide reliable protection against premature system failure and downtime, we recommend the use of a triflex® R e-chain®, especially to bridge axes 3-6. The dynamic change in length that results from the robot's movement is compensated by the triflex® R retraction systems. Constantly guiding the igus® e-chain® package in a defined manner to prevent the formation of loops in the robot's working area.
