These aluminium rigid shaft couplers allow you to couple two size shafts together. The design provides high torque capacity, stiffness, and zero backlash. They can be used for connecting motor shafts to drive shafts, or two different-sized shafts. These shaft couplers have a length of 40mm, a outer diameter of 24.5mm, and couple 8mm to 1/4" shafts. Clamp action eliminates shaft damage caused by set screws.
This coupler matches the shaft diameter of our 125 oz.in Stepper Motor.
