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.
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.
At a German motor vehicle manufacturer, 50 Epson Scara robots have been in continuous operation with our Scara solution since 2016 and have so far achieved a cycle count of over 17 million.
Here you can see our test setup for the product expansion.

It shows the new rotary unions still as 3D printed parts, which together with the e-rib form the Scara cable solution.
This video was recorded in the igus test lab on 25/11/2020 and shows the functionality of the Scara cable solution even more clearly.
Rotary linkage + e-rib ensure optimum unity.
