Definition of Ball and Socket Joints

Ball and socket joints—are also referred to in some contexts as axial articulation joints—are mechanical bearing assemblies designed to enable multi-axis angular displacement and rotational motion between two connected components.

The joint consists of a spherical male element (the ball) and a concave spherical female housing (the socket). This geometry forms a spherical plain bearing interface, enabling the connected parts to pivot, rotate, and accommodate misalignment while transmitting load.

At igus, we have a range of both plastic and metal ball and socket joints in our igubal range.
