JSUMO JS4320 Aluminum – Silicone Wheel Pair (43mm x 20mm) Pair (4mm Hole)

The SUMO JS4320 Aluminum-Silicone Wheel Pair is engineered to provide outstanding traction and reliable performance for competitive robotics and precision motion applications. The wheel combines a lightweight yet strong aluminum hub with a soft silicone tire, creating an optimal balance between durability and grip. The 20 Shore A silicone tire offers excellent surface contact, helping robots maintain traction during high-force pushing and maneuvering tasks. This makes the wheel particularly suitable for sumo robot competitions where grip and control are critical factors. Featuring a 43 mm diameter and 20 mm width , the wheel provides a stable footprint while remaining compact enough for lightweight robotic designs. The 4 mm center bore and M4 setscrew allow secure installation on compatible motor shafts, ensuring reliable power transmission and minimizing slippage during operation. Designed for demanding environments, the JS4320 wheel is an ideal solution for robotic systems that require high traction, stability, and precise movement control.
