JSUMO JS5530 Robot Wheel 55x30mm Pair

The SUMO JS5530 Robot Wheel Pair is specifically developed for competitive sumo robotics where traction, strength, and reliability are critical to success. Designed for Japanese-style magnetic sumo robots, these wheels feature precision-machined aluminum hubs combined with a high-quality rubber tire permanently bonded through a vulcanization process. Unlike conventional wheel assemblies, the rubber tire is directly molded onto the aluminum hub, creating a stronger and more durable connection capable of withstanding the intense forces generated during sumo competitions. This construction minimizes tire slippage and enhances power transfer from the motor to the competition surface. The wheel's 55 mm diameter and 30 mm width provide a large contact area, allowing superior grip and pushing performance. The 64 Shore A rubber compound offers an optimal balance between traction and durability, making it suitable for repeated use in demanding tournament environments. The JS5530 wheel is equipped with M3 tapped gear mounting holes and an M4 tapped setscrew for secure shaft attachment. It is designed to fit compatible gear bundles directly, simplifying installation and ensuring reliable mechanical integration. Recognized by many successful competitors, the JS5530 has become a popular choice for builders seeking maximum performance in magnetic sumo robot competitions.
