A sturdy metal ball caster made from 1 mm stamped steel plate, capable of supporting loads up to 15 kg. At just 37 g and 20 mm tall, it provides smooth omnidirectional movement without adding significant weight to your robot chassis.

The caster uses 40 small bearing balls around the main 15 mm steel ball for low-friction rolling in any direction, making it ideal as a third contact point on two-wheeled robot platforms.
