Ball cup for Demag AC80-1

The ball cup, identified as part number 551 213 40, functions as a critical housing within the articulation systems of the Demag AC80-1 crane. It is designed to accommodate a ball or spherical element, forming a complete ball joint assembly that allows for multi-axis movement between two structural or mechanical components. This configuration provides a flexible pivot point necessary for steering, suspension, or control linkage systems where both load-bearing capacity and range of motion are required during machine operation.

This component is specifically engineered for the Demag AC80-1 crane. The internal surface geometry is machined to match the spherical profile of the mating ball, ensuring proper seating and movement. Regular inspection of this component is necessary to monitor for signs of wear or excessive clearance, which can affect the precision and stability of the crane's articulation points.

In heavy machinery, ball cups are used in various linkage assemblies to translate linear or rotational forces while accommodating misalignment or changes in angle. By housing the spherical joint, the cup maintains the alignment of the connection, allowing the assembly to pivot smoothly under load while protecting the joint from external contaminants.
