Lars Butenschön | 4. January 2019

The various influences that affect the lifespan of a plain bearing are relatively trivial. It´s easy to imagine that a truckload of fine dust is rather less helpful for a long bearing life. Also, that 500 ° C ambient temperature can cause difficulty in choosing the right lubricant, results in few raised eyebrows. And yet, often times […]

Plastic bearings for high loads? What does high load actually mean?

Lars Butenschön | 4. December 2018

There is a saying among german conservative engineers going like this: “Wer Kunststoff kennt, nimmt Stahl”. “Those familiar with plastics use steel instead”. To be honest I didn’t hear this in quite a while now. But it´s still in the heads of many engineers. Even if they don´t know a word of german. In the […]

angle sensors in the robolink joints

Martin Raak | 6. February 2014

We have noticed, that for some people it is not clear how our angle encoders work and how to make use of it. Here are some facts about them: 1) we use incremental encoders from AMS (AS5304A), absolute encoders are not possible in the current design, 2) in order to define the ZERO position for […]
