Frequently asked questions

What is this coupling used for?

It connects two shafts with different diameters, for example a motor shaft to a lead screw, so the motor can drive the screw.

How do I know it fits my shafts?

Check that one shaft matches the 10 mm bore and the other matches the 14 mm bore. Measure both shafts before fitting.
