No more greasing: For balers, loader wagons, manure spreaders, tippers and field sprayers, Rockinger Agriculture GmbH has developed ball couplings called KS80 with a high-performance plastic from the iglidur® series, which igus® developed especially for the company. The coupling consists of a coupling ball and a drawbar socket, which are installed in the height adjustment.
As usual, the pulling pan is positioned on the ball head from above. It is secured against unintentional uncoupling by means of a hold-down device and creates a clearance-free connection. The special feature of this coupling only becomes visible when you look into the towing socket. This contains the wear insert made of high-performance plastic, whose wear resistance has been proven in laboratory tests.
In a fatigue test, the inserts withstood two million load changes - with a drawbar load of 4.5 tonnes. The company does the maths: If a third of the tractors in Germany are equipped with a KS80 and wear insert, this means that around 8,300 couplings can manage without lubrication. Eight tonnes of grease per year could be saved.
