N20 Caster Wheel

The N20 Caster Wheel is a compact, lightweight ball-type omnidirectional support wheel designed for small robotic platforms and DIY projects. It is commonly used with N20 gear motor–based robots, mini smart cars, and 3PI-style chassis to provide smooth balance and stable movement.

This caster wheel features a steel ball mounted inside a durable plastic housing, allowing 360-degree free movement with minimal friction. It is not a drive wheel but acts as a support wheel, improving maneuverability and reducing drag during turns and directional changes.

Ideal for educational robotics, hobby projects, line-following robots, and mini autonomous vehicles, the N20 caster wheel is easy to install and highly reliable for lightweight applications.
