Is it possible to manufacture special products such as eccentricity and different diameters?

Yes. Please specify your requirements.

Which position in the coupling should I insert the shaft?

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.

Please note that the MISUMI Pune office and warehouse will be closed on November 20th due to the state election.
