Pololu 1127 - Solarbotics RW2i Wheel (internal set screw)

The Solarbotics RW2i rubber robot wheel has a black, anodized aluminum hub with a generously thick 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.

This rubber robot wheel has a diameter of 1.23 inches (31.2 mm) and is 0.52 inches (13.2 mm) wide. 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 gearmotors such as our micro metal gearmotors and the GM12a, GM13a, GM14a, and GM18mini metal gearmotors.
