Question: Why is my disc coupling slipping on the shaft?
Answer:After asking for some clarification on the part number we determined it was MDCD33-10-10-A which has a rated torque of 11.3 Nm. When clarifying this system motion we found that there is a gradual ramp up and ramp down as the coupling starts and stops but nothing to actually derate the coupling. We then asked about shaft size and tolerancing. Our shaft tolerance is +0.000/-0.013mm. When the customer reviewed their shaft tolerance it was actually +0.000/-0.1mm. The customer was most likely having installation issues because this far exceeds the clamping range the disc coupling is capable of. They ended up swapping the shafts they were using and this fixed their issue.
