JSUMO JS2114 Micro Silicone Wheel Set (21 x 14mm – Pair)

The JSumo JS2114 Micro Silicone Wheel Set is a premium wheel solution developed for small-scale robotics applications where high traction, lightweight construction, and precise control are essential. Designed specifically for micro robots, the wheel combines a durable metal rim with a high-friction silicone tire to maximize grip and driving performance. With a diameter of 21mm and a width of 14mm , the JS2114 is ideal for compact robot platforms that require efficient power transfer and excellent maneuverability. The silicone tread width of 12mm provides a substantial contact area, improving traction while maintaining smooth movement. The wheel uses a 20 Shore A silicone compound , delivering a balance between grip, durability, and wear resistance. This makes it suitable for competitive micro sumo robots, maze-solving robots, and other small robotic systems operating on smooth surfaces. A precision-machined metal hub provides strength and durability, while the 3mm center bore and M3 threaded setscrew allow secure attachment to compatible motor shafts. The wheel design has been successfully used in micro sumo robot platforms such as the XS1 Micro Sumo Robot, demonstrating its effectiveness in competitive environments.
