This deep pot magnet with a diameter of 32 mm and a smooth housing has a remarkable adhesive force of approx. 34 kg. This high magnetic adhesive force is achieved because the forces of the neodymium magnet inside the steel cylinder are focused toward the holding surface. These deep pot holding magnets with smooth housing can be mounted by press-fitting or glueing, for example.
What applies to pot magnets, also holds true for deep pot magnets: The full adhesive force is achieved with a smooth ferromagnetic counterpart of sufficient thickness and with direct and flush contact of the deep pot magnet.
