Motor Test Bench - Metal Bellows Coupling EKN 45/48
First they were using a stiff coupling because it was the cheapest solution. Due to misalignment problems the couplings broke weekly. RINGFEDER POWER TRANSMISSION delivered a cost free sample for testing, the result was a 5-10 times higher life time. Even though our coupling has a higher purchasing price it is cheaper to use ours, because we could lower the yearly demand from 5000 to 800 couplings.
