Frequently asked questions
Which shaft sizes does it fit?
The listing gives inner diameters of 5 mm and 8 mm. Check that your motor shaft and driven shaft match these bores before ordering or fitting.
Why use a flexible coupling instead of a rigid one?
A flexible coupling tolerates small misalignment between shafts, which reduces stress on the motor bearings and on the lead screw.
