Frequently asked question (FAQ)

Question: Is it possible to manufacture special products such as eccentricity and different diameters?
Answer: Yes. Please specify your requirements.
Question: Which position in the coupling should I insert the shaft?
Answer: Insert the shaft up to the width of clamping hub (main body). If the shaft is shorter than the width, the allowable torque will not be satisfied.
