Description
7mm Brass Hex Coupling (Short) is a compact, high-precision metric shaft adapter designed to connect a 7 mm motor output shaft to wheels, gears, or robot chassis hubs securely using a rigid hexagonal interface.
⚙️ Technical Specifications
- Inner Diameter (Bore): 7 mm (Designed to slide onto standard 7mm 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: Includes 1 Coupling and matching set screws
🛠️ Practical Applications
- Robotics Projects: Essential for connecting specialized heavy-duty DC gear motors or stepper motors to rubber wheels or mecanum wheels.
- RC Vehicles: Used in custom large-scale remote-controlled trucks, rock crawlers, and robotic rovers to transfer high rotational torque to hex-drive wheels.
- DIY Smart Cars: Ideal for building customized Arduino or Raspberry Pi-powered mobile robots requiring stable wheel hubs.
- Precision Hardware: Functions as a compact extension or adapter for custom mechanical linkages in low-clearance spaces.
