Robot builders often find that the trickiest part of a robotics project is making the wheels. First you need to find a suitable tire/wheel combination, then you must figure out a way to attach a sprocket so that it will handle the torque of a geared-down drive motor. Our wheel/sprocket/bearing combination will solve those problems for you!
The hard plastic wheel reduces traction but also makes turning easier and reduces power consumption while turning. In the BattleKits robots, Two 4-19HP wheels can be used in combination with two regular high-traction 4-19 wheels. This will give a good combination of traction and ease of turning in robots that do not require uncompromised traction. Educational and experimental robots along with robots intended to operate on carpet may work best with two, (or even four), hard plastic wheels.

|4in. ||19 ||1.0 lb ||375 ||9 |
* Indicates the speed at which a vehicle would travel if the wheel was driven by chain from a motor output shaft with a 9-tooth sprocket which is revolving at 1700 RPM. (As they are in the BattleKits when using our E30-150 motors with speed reducer).
For use with #35 chain.
Contains one wheel-sprocket assembly.
