About this product

Which motor shafts does this coupler fit?
The 5×8 size means one end takes a 5 mm shaft and the other end takes an 8 mm shaft, so it suits a 5 mm motor shaft joined to an 8 mm lead screw or similar. Measure your shafts before fitting, because the bore must match the shaft diameter.
Can it be used with a stepper motor on a 3D printer?
Yes, this is its common use. Tighten the set screws on both ends onto the flats of the shafts, and check that the coupler is centred so the motor does not wobble during movement.
