External Threaded Ferrite Pot Magnets

An external(male) threaded ferrite pot magnet is ferrite magnet assembly with disc magnet and steel shell/cup.There is a male threaded stem on the top of the steel shell.The steel shell protect the disc ferrite magnet from damaging, also enlarge the magnetic force. With the steel shell housed, there is only one magnetic surface used, the optimal surface is steel and iron.Due to the external threaded stem, it it more easy to used external threaded ferrite pot magnets .

To offer the strongest magnetic force,anisotropic ferrite magnets are adopted for the male threaded ferrite cup magnets
Our male threaded ferrite cup magnets are even stronger! The steel pot/cup can be made with chrome plated, nickel plated, zinc coated and paint coated, even rubber coated.The below table shows the standard sizes of ferrite pot magnets with external thread stud. External threaded ferrite pot magnets can be used as magnetic holder and mounting magnets.

The large external threaded ferrite cup magnets can be used for heavy duty application. The strong and permanent magnetic force will be kept for ever. We have full standard sizes range for ferrite cup (pot) magnets with external(male) threaded stud with diameter from 10mm to 125mm, and magnetic holding force is up to 130kgs. If no standard male threaded ferrite cup magnets can work for you,then try our our external threaded pot magnets of neodymium.

The magnetic pull force was measured on a 10 mm thick polished steel plate at room temperature. In special cases, the maximum deviation may be - 10%. Generally, it usually exceeds the value. Small scratches and breakage in the magnetic material do not affect the pull force of the whole ferrite cup magnet. Depending on the type of application (installation, temperature, thickness of the object being sucked), the pull force is greatly affected. The tension value is only for reference, not as a standard to measure the quality of the ferrite pot magnets.
In addition to standard sizes, we also offer custom solutions for external threaded ferrite cup magnets.
