Product Description

The Round Ball Bearing Caster Wheel is a simple yet essential component for robotics and DIY projects. Designed to rotate freely in all directions, it’s commonly used as a front support wheel in differential‑drive robots. The built‑in ball bearings ensure smooth rotation with minimal drag, allowing robots to move effortlessly.

Made with a stainless steel ball for rust resistance and durability, this caster wheel is ideal for line follower robots, obstacle‑avoiding robots, and other mobile platforms. Its compact size and lightweight design make it easy to mount under robots or larger objects, enabling smooth rolling and stable support.
