High-torque 20mm to 20mm jaw shaft coupling for motion
✔️ 20mm to 20mm shaft, 66x40mm overall, M6 screws, aluminum pack 1

This jaw style shaft coupling is a general purpose power transmission connector designed to link two 20mm shafts. It's widely used in motion control, servo systems, and CNC setups to transmit torque while damping vibration and accommodating slight misalignment.

✅ Material: aluminum alloy, silver tone
✅ Shaft compatibility: 20mm to 20mm (0.79" to 0.79") bore
✅ Overall size: 66 x 40 mm (2.6" x 1.57")
✅ Features: vibration damping and misalignment tolerance to protect drive components
✅ Thread: M6 set screws for secure mounting

💡 What is a shaft coupling and how does a jaw type help with motion control?

This handy device connects two rotating shafts and transmits torque while dampening vibration and absorbing misalignment.

- It transmits torque between shafts while dampening vibration - It handles small misalignment to protect connected components - It is handy for servo, motion control, and CNC systems
