Magnetic ball joints, magnetic pole position ball, Joint Magnetic ball through the magnet and the ball joint binding, the principle is the use of magnetic spheres do adsorption position rotates to use. Thus, the movable range of the ball will be greatly wide, can be rotated 180 °. Junction of the magnet and the ball is spherical ball combination can not scratch. You can also replace the magnet sphere and can work within the same model By Industry Optical equipment, lighting, fixed surveillance cameras, medical devices, robot joints
Magnetic Ball Joints is a holding Device which has flexible joints with a diameter10mm steel ball held by powerful rare earth magnets contained in the magnet cylinder. And the magnetic ball joints allow the steel ball a full 360°rotation on a 180°axis. This caused even if the ball comes off from the magnet cylinder, no damage can be made and the joints can work just as well as before when reset.
Due to the use of high-energy rare-earth magnets, magnetic ball joints have a very strong holding force. The resulting displacement force of the ball is strong enough to hold the optical systems of cameras, lighting fixtures or laser units without requiring a mechanical fixation. And there are many models of the magnetic ball joints with threaded, showed in below diagram. ndfeb magnetic ball joint k310
