Magnetic Ball Joints

A holding device used for cameras, light fixtures, optical devices, and other applications.

The magnetic ball joint assembly allows the steel ball a full 360° rotation on a 180° axis. This is made possible by the combination of a steel ball (10 mm diameter) and a powerful rare earth magnet contained in the magnet cylinder. The ball comes threaded as in the diagram for different sizes.

For magnetic ball joints with other dimensions please consult us for further information.
