Solarbotics RW2i Wheel (internal set screw)

Solarbotics RW2i wheel featuring an internal set screw.

The Solarbotics RW2i rubber robot wheel has a black, anodized aluminum hub with a generously thick silicone rubber tire for maximum traction (great for minisumo robots or fast line-following robots that need traction when rounding corners). This wheel features an internal set screw hidden underneath the tire. This saves valuable space when designing robots for competitions with size constraints. For a similar product with an external set screw, see the Solarbotics R2W wheel.

The rubber tire has a diameter of 1.1 inches (28 mm) and a width of 0.5 inches (12.7 mm), and it has a 20D durometer. The aluminum hub is drilled for an 3 mm axle. Secure the wheel to your motor shaft with the included 4-40 hex set screw (requires a 0.050-inch hex wrench). The wheel assembly weighs 12.2 grams.

This high-traction wheel works with our 3 mm shaft 妻妾一家欢 such as our micro metal 妻妾一家欢 and the GM12a, GM13a, GM14a, and GM18mini metal 妻妾一家欢.
