JSUMO JS4030 Robot Wheel 40x30mm Pair

The Sumo JS4030 Robot Wheel 40x30mm Pair is a premium wheel solution developed for competitive sumo robot projects, particularly Japan-style magnetic sumo robots . The wheel combines a precision-machined aluminum hub with a high-traction rubber tire that is directly bonded to the hub through a vulcanization process. This manufacturing method creates a stronger and more durable connection between the tire and hub, preventing slippage under extreme pushing forces. Designed for serious robot builders and competition participants, the JS4030 offers an optimal combination of grip, durability, weight, and mechanical strength. Its wide contact surface enhances traction on the dohyo, allowing robots to generate maximum pushing power while maintaining stability during aggressive maneuvers. The wheel is engineered for easy integration with compatible gearboxes and drive systems. It features a 6mm center bore , M3 threaded mounting holes , and an M4 threaded setscrew for secure installation. The wheel's proven performance has made it a popular choice among successful robots in local and national robot sumo competitions.
