Technical details and manufacturing context for Rotational Joints

Definition
Rotational joints are critical components within spray manipulators that provide controlled rotational degrees of freedom, allowing precise positioning and movement of spray nozzles or applicators. They facilitate smooth articulation and orientation changes necessary for accurate coating, painting, or treatment applications across various surfaces and geometries.
Working Principle
Rotational joints operate by providing a bearing-supported interface between connected segments, allowing one part to rotate relative to another around a fixed axis. They typically incorporate seals to contain fluids or gases while maintaining rotational capability, with precision machining ensuring minimal play and consistent movement under load.
