Ball casters provide smooth, omni‑directional movement for compact robots and mobile platforms. They are built around a spherical ball, available in plastic or metal, encased in a two‑part ABS housing that snaps together, protecting the ball and any internal bearings or rollers. Small‑diameter options (3/8 in to 1 in) keep the overall height low, allowing tight integration under chassis or sensor mounts, while larger balls increase load capacity. Plastic balls and rollers give lightweight, low‑cost solutions, whereas metal balls and ball‑bearing assemblies deliver higher durability and reduced friction for more demanding applications. The modular spacer system lets users adjust caster height to suit different frame designs, ensuring reliable operation and easy replacement across a range of robotic and automation projects.
