N20 Vacuum Steel Ball Universal Omnidirectional Caster Wheel

The N20 Vacuum Steel Ball Universal Omnidirectional Caster Wheel is a high-quality passive support wheel designed to provide smooth, stable, and omnidirectional movement for robotic platforms and autonomous vehicles. Featuring a precision steel ball housed in a durable casing, this caster wheel rotates freely in all directions, reducing friction while improving balance and maneuverability.

This compact caster wheel is widely used as the third support wheel in 2-wheel differential drive robots powered by N20 geared motors. Its omnidirectional design allows robots to move effortlessly in any direction while maintaining stability on flat surfaces.

Manufactured from durable engineering materials with a polished steel ball, the caster offers excellent wear resistance, quiet operation, and long service life. It is suitable for lightweight robot chassis, smart cars, line-following robots, obstacle avoidance robots, AGVs, educational robotics kits, and embedded system projects.

Compatible with Arduino, ESP32, Raspberry Pi, STM32, microcontroller-based robots, and DIY electronics, this caster wheel is an essential component for building reliable and efficient robotic systems.
