Aluminum Flex Shaft Coupler – 3mm to 5mm


Aluminum Flex Shaft Coupler – 3mm to 5mm



Need to connect two shafts together? This flex coupler has a helical cut that allows two shafts that are not perfectly aligned to be joined together while reducing binding. These are a little springy in the X, Y, and Z axis but not in the rotational axis meaning they will not cause additional backlash. The coupler has two set screws on each side to hold it in place. This specific coupler is designed to fit a 5mm shaft on once side, and 3mm on the other side.

These couplers work great with our stepper motor!
