Scara cable solution

igus has developed the e-rib to safely guide cables guided by corrugated hose. In combination with the reinforcements at both ends and the sag of the corrugated hose as well as the rotary unions, this solution is ideally suited for high-speed SCARA applications.
 
The e-rib fills the joints of the corrugated hose to stabilise it in such a way that it can only move in one direction. The corrugated hose has an unsupported length due to the lateral guide elements. As a retrofit, the e-rib allows an upgrade of existing applications in just a few steps. e-rib is independent of the hose manufacturer. At first we are offering this solution in the nominal width of 29mm.

What is behind the Scara cable solution?

Corrugated tube dynamically reinforced

The reinforcement for existing corrugated tube systems. The e-rib is clipped onto a corrugated hose. The new sizes are independent of the hose manufacturer. The e-rib stabilises the corrugated hose so that it can only move in one direction. With its lateral guide elements, the corrugated hose requires no support along its length due to the e-rib.
Initially we offer the nominal width 29 for the Scara robots. 
1 = e-rib fixing by means of cable ties
2 = e-rib with definition of the nominal width

Customer application of a Scara cable solution

in continuous operation for over 3.5 years (2020)


At a German motor vehicle manufacturer, 50 Epson Scara robots have been in continuous operation with our Scara solution for over 3.5 years (from 2016) and have so far achieved a cycle count of over 20 million.  

  • Largely maintenance-free
  • Significant increase of the system service life
  • Can be retrofitted with little effort

e-rib in the igus test laboratory


The video shows the movement or deflection of a corrugated hose without e-rib compared to an identical corrugated hose with e-rib reinforcement.
 
The deflection is significantly minimised and the service life of the system is increased.
