An arm is a structural linkage component that connects and transmits motion or force between two points within a mechanical assembly. It maintains correct positional relationships between connected parts, allowing the system it belongs to — whether a control linkage, articulation joint, or mechanical actuator — to operate smoothly and accurately. When an arm becomes bent, cracked, or worn at its pivot points, the affected system can develop unwanted play or bind, leading to imprecise operation and accelerated wear on surrounding components.
