Aluminum Flex Shaft Coupler – 0.250″ to 5mm


Aluminum Flex Shaft Coupler – 0.250″ to 5mm


SKU: ROB-149


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.

This specific version is designed to couple a 1/4” shaft to a 5mm shaft and is perfect for connecting our large 125 oz-in Stepper Motor to a 5mm shaft or any of our NEMA17 steppers to a 0.250″ shaft.


  • 5mm to 0.250″ (6.35mm) coupling
  • Diameter: 19mm
  • Aluminum construction
  • Length: 25mm

In stock (can be backordered)
