Caster/Castor Wheel (Round Ball Bearing for Robotic Project)

A simple castor wheel that can rotate in all directions. It is commonly used as a front wheel in differential-driven robots. The ball bearings inside it provide smooth rotation of the wheel enabling less drag for the robot. Can be found in line follower, obstacle avoided, and other robots. It can be mounted under robots or other larger objects to enable easy movement or rolling of the robots or objects. The caster balls are made up of stainless steel to avoid rust and to improve product longevity.
