The Robot Car Wheel 50mm x 20mm is a black and white lightweight durable wheel with 50mm outer diameter, 20mm width, 6mm shaft hole diameter, and rubber grip tyre, designed for standard DC gear motor robot car builds. This 50mm robot wheels variant has the widest body in StemVolt’s wheel lineup at 20mm — wider than the 11mm body of the 30mm micro wheel, 13mm body of the 35mm RC wheel, and the 15mm body of the 45mm and 65mm BO motor wheels, giving this wheel the largest rolling contact patch of any wheel in the range and proportionally greater grip on smooth flat surfaces.
The 50mm robot car wheel’s 6mm shaft bore is the standard bore size for DC gear motors used in Arduino-based robot platforms — distinct from the 2mm micro bore of the 30mm toy wheel and the unspecified bore of the 35mm variant. This 6mm bore makes the wheel for dc gear motor directly compatible with the most common geared DC motor output shafts without requiring adapters, hex couplers, or modifications. The rubber grip surface provides confirmed traction advantage over hard plastic wheels of identical dimensions.
this 50mm wheel for projects’ 20mm width requires matching 20mm of axle shaft clearance in the chassis motor bracket — builders using narrow motor brackets need to verify adequate lateral clearance before installation. Explore Robotics components at StemVolt.
