JSUMO JS7444 Aluminum-Silicone Wheel Pair (74mm Diameter)

The SUMO JS7444 Aluminum-Silicone Wheel Pair is engineered for demanding robotic applications where maximum traction, durability, and mechanical reliability are essential. Designed specifically for medium to large robots, these wheels combine robust CNC-machined aluminum hubs with thick, high-grip silicone tires to deliver exceptional performance in competitive and industrial environments. The wheels feature a large diameter and wide tread profile that improve stability, obstacle handling, and surface contact. The soft 20 Shore A silicone compound provides outstanding grip, making these wheels particularly effective in applications where pushing force and traction are critical, such as sumo and combat robots. A precision 6 mm center bore ensures compatibility with standard motor shafts, while the integrated M5 tapped setscrew hole provides a secure mechanical connection that minimizes slippage under heavy loads and high torque conditions. With a substantial weight of 229 grams per wheel , the JS7444 wheels offer excellent momentum and traction for larger robotic platforms. Their superior surface finish and carefully manufactured construction make them a reliable choice for advanced robotics projects.
