Ball joints are primarily categorized into two types based on their operating principles and structural characteristics: rotating ball joints and fixed ball joints.
Rotating Ball Joints
Rotating ball joints permit rotational movement within a certain range between two connected components. These joints typically feature a large spherical contact area, effectively distributing loads and reducing stress concentration. Rotary ball joints are widely used in machinery, robotic joints, and other applications requiring frequent motion.
Fixed Ball Joints
Fixed ball joints are primarily used to connect stationary structures, offering resistance to impact and vibration. Typically constructed from rigid materials, they provide high load-bearing capacity and stability. Fixed ball joints play a vital role in aerospace, bridge construction, architecture, and related fields.
