Description
3mm Brass Hex Coupling (Short) is a compact, high-precision metric shaft adapter designed to connect a 3 mm motor output shaft to wheels, gears, or robot chassis hubs securely using a rigid hexagonal interface.
⚙️ Technical Specifications
- Inner Diameter (Bore): 3 mm (Designed to slide onto standard 3mm motor shafts, including D-shape and round shafts)
- Outer Profile: Hexagonal (Hex) shape (Typically 12mm hex size for standard RC/robotics wheel compatibility)
- Length: Short profile (Compact length minimizes shaft overhang and reduces rotational wobble)
- Material: Premium Solid Brass (Offers excellent durability, wear resistance, and low friction)
- Fastening Method: Dual Set Screws (Grub Screws) along the side to lock firmly onto the flat side of the motor shaft
- Package Contents: Typically includes 1 Coupling and matching set screws
🛠️ Practical Applications
- Robotics Projects: Essential for connecting micro DC gear motors (like N20 motors) to rubber wheels, omni wheels, or mecanum wheels.
- RC Vehicles: Used in custom remote-controlled cars, trucks, and boats to transfer rotational power to hex-drive wheels or props.
- DIY Smart Cars: Ideal for building small-scale Arduino or Raspberry Pi-powered mobile robots requiring compact wheel hubs.
- Precision Hardware: Functions as a compact extension or adapter for custom mechanical linkages in low-clearance spaces.
