This deep pot magnet with a diameter of 25 mm and internal thread M6 has a remarkable adhesive force of approx. 19 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. This deep pot holding magnet can be securely mounted thanks to the internal thread.
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.
