The FingerTech Urethane Sumo Wheel 2.50" is a high-performance wheel designed for competitive robotics applications. It features a high-traction polyurethane tire molded around a robust, machined, and anodized aluminum rim. This construction ensures durability and optimal performance in demanding environments.
The tire tread is composed of Shore A20 polyurethane, renowned for its superior traction capabilities, making it an ideal choice for sumo robots weighing up to 6kg. The black anodized aluminum rims are engineered with machined rings and captive through-slots, ensuring the tire tread remains securely in place during operation.
This wheel is available in various colors, each made to order, allowing for customization to suit specific aesthetic preferences. The rim material is crafted from 6061 aluminum, providing a lightweight yet sturdy foundation for the wheel. The wheel's dimensions include an outer diameter of 63.5mm, a width of 38.1mm, and an inner diameter of 38.1mm, with a total weight of 123 grams.
Note: Clean the tires with isopropyl alcohol wipes before each match to maintain optimal traction.
