robolink D test area

Martin Raak | 28. August 2015

we do several lifetime and performance tests with our robolink D joints. Until July, main topics were material and geometry optimisations for the gear and bearing components. Nowadays, we do lifetime tests for different joint types at different loads and speeds. The attached film shows or test unit with currently 9 test places, it will […]


RL-D different versions, pricing

Martin Raak | 18. August 2015

We have defined 3 different quality standards for our robolink D joints and I want to explain the background of this issue. The 3 qualities are: “low cost”, “standard”, “high end” The main performance differences are stiffness, friction, precision (reverse play) and on the other hand cost. For size -20 and -30, the price difference between […]


STEP data RL-D joint kit

Martin Raak | 19. May 2015

The Basic idea of our NEW RL-D Joints is, that every Joint can be composed out of several components (Joint kit). Main differentiations are: # Rotary sliding bearing igus PRT-01 (aluminum table with iglidur J sliding elements) or PRT-02-AL (aluminum ring with compact plastic ring made of iglidur J4) or PRT-02-LC (outer aluminum ring replaced […]


robolink D data sheets and STEP data

Martin Raak | 15. May 2015

Please find attached current (preliminary) data sheets for our new robolink D Joints. These Joints exist in 3 sizes: -20, -30 and -50 (based on the Dimensions of our rotary sliding tables PRT). RL-D-xx-101 RL-D-xx-102 RL-D-xx-101: symmetrical Joint with 2 PPRT for vertical Installation (used in our robotic arms), tech data RL-D-101 _D-ENG_.pdf (167.44 kb) […]


robolink application under water

Martin Raak | 28. January 2015

This submarine robot has been developped by our german customer Habib Nasri from Leibnitz University Hannover, iPeG Institute. It is fully submersible and it is gesture controlled. It contains 1 simple arm with 2 DOF and one more complex arm with 4 DOF, all robolink joints are equipped with our “under water angle sensors”. The 6 […]
