JSUMO JS4311 Aluminum – Silicone Wheel Set (43 x 11mm – Pair)

The SUMO JS4311 Aluminum - Silicone Wheel Set is specifically designed for lightweight robotic applications where high traction, low weight, and precise movement are essential. Its large diameter and slim profile make it particularly suitable for mini sumo robots , line follower robots , and other compact autonomous robotic platforms. Each wheel features a precision-machined aluminum hub combined with a high-quality silicone tire that delivers excellent grip on a wide variety of surfaces. The soft 20 Shore A silicone compound maximizes surface contact, allowing robots to maintain traction during rapid acceleration, sharp turns, and competitive maneuvers. With a 43 mm diameter and a narrow 11 mm width , the wheel provides smooth rolling performance while minimizing weight and rotational inertia. The 8 mm silicone tire width ensures efficient contact with the ground without adding unnecessary bulk, making it ideal for fast and agile robots. The 3 mm center bore and integrated M4 setscrew enable secure attachment to compatible motor shafts, ensuring reliable power transfer and stable operation during demanding robotic applications.
