5mm coupling for Robot Smart Car Wheel

The 5mm coupling for robot smart car wheels is a shaft coupling sized for 5 mm motor shafts that connects the motor to the wheel hub. It lets you mount robot car wheels on DC gear motors whose shaft does not fit the wheel directly, and it passes the motor's torque to the wheel through a firm, centred connection. It is a useful part when building, upgrading or repairing 2WD and 4WD robot cars, rovers and other wheeled robots.

5mm Coupling Specifications

• Shaft size: 5 mm
• Type: motor-shaft-to-wheel coupling (hub adapter)

• Quantity: 1 coupling

5mm Coupling Applications

• Robot cars and rovers built with metal DC gear motors
• Fitting larger wheels to a robot chassis
• Replacing a worn or lost wheel coupling
• Robotics competitions, school clubs and STEM projects

What's in the Box

• 1 × 5 mm coupling for robot smart car wheels

Tip: Measure your motor shaft with a caliper and check whether it is round or D-cut before fitting. If the coupling uses set screws, tighten them against the flat of a D-shaft so the wheel cannot slip, and add a drop of thread-locker so vibration does not loosen them. Use one coupling per driven wheel.
