The JSumo Atom Silicone Wheel 37x34mm Pair is built for small robots that need more grip and a wider contact patch. With a machined aluminum hub and soft silicone tire, this wheel set is a strong fit for mini sumo robots, line follower robots, and other lightweight drive builds that need better traction during fast starts, turns, and pushes.
Why builders choose this wheel set
- High traction: Soft silicone tire helps improve grip on smooth robot arenas and line tracks.
- Wide wheel profile: The 34 mm body width gives a larger contact area for better stability.
- Strong hub design: Machined aluminum hub adds a more solid feel than basic plastic wheels.
- Easy shaft locking: M4 tapped setscrew helps secure the wheel to the motor shaft.
- Good for compact robots: Sized for lighter builds where grip matters more than weight savings.
What you can build
These wheels are a good match for compact competition and learning robots. They work well in mini sumo projects where push force and surface grip matter, and they also make sense for line follower robots that need smoother control through curves.
They can also be used in custom two-wheel drive robot platforms, classroom prototypes, and mechanical test rigs where you want a wider wheel with a soft outer tire.
