Solarbotics RW2 rubber wheel with black aluminum hub.

The Solarbotics RW2 rubber 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 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 1/8-inch (3.18 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 grams. If you are looking to shave some width off your robot design, consider the Solarbotics RW2i wheel, which is a similar design with but has an internal set screw.

This high-traction wheel works with Pololu's 3 mm shaft gearmotors such as Pololu's micro metal gearmotors and the GM12a, GM13a, GM14a, and GM18mini metal gearmotors.

Included Parts

  • One hub
  • One tire
  • One set screw

A 0.05″ hex wrench (not included) is required for mounting the wheel. The wheels are sold individually, NOT in pairs.
