Aluminum alloy 5*5mm CNC machined motor rigid shaft coupler

Precision 5mm to 5mm CNC-machined aluminum alloy rigid shaft coupler designed to connect stepper motors, servo motors, or lead screws with zero backlash. Ideal for 3D printers, CNC routers, robotics, and small DIY machinery requiring high torque transfer and strict axial alignment.

Key Features

• Zero Backlash & High Torque: Solid aluminum body ensures direct, rigid power transmission without flex.

• Precision CNC Machined: Holds tight tolerances for a secure, slip-free fit on 5mm shafts.

• Durable & Lightweight: Anodized aluminum alloy provides corrosion resistance and low rotational inertia.

• Includes Set Screws: Ships with M3/M4 grub screws for quick and easy installation.
