About this product
A machined aluminum flexible shaft coupler that joins a 10 mm shaft to a 14 mm shaft using set screws. Its spiral cut tolerates slight misalignment between shafts and reduces bending stress, while staying stiff in rotation so backlash is not increased. It is commonly used in CNC machines and 3D printers to connect a stepper motor to a lead screw.

Frequently asked questions
Can it handle slightly misaligned shafts?
Yes. The spiral cut lets the coupler flex in the X, Y and Z directions to accommodate slight misalignment between the two shafts.
How do I secure it to the shafts?
Tighten the set screws on both sides. Each side has two set screws for a secure attachment.
