Neodymium Countersunk Ring Magnets OEM Permanent Magnet | Fullzen Technology

Short Description:

Countersunk cup neodymium magnets is a functional type of strong magnet that shows a standard straight hole on one end surface, but has an angled countersunk screw hole on the other surface. It is usually measured by outside diameter, through hole diameter, major diameter, depth and angle. The angle is generally 90 degrees. There are often projects with magnets in our living environment, which are widely used in handicrafts, jewelry, photos, greeting card displays, and can even be used to make DIY magnet projects and more.

Fullzen Technology is a super strong magnet factory, we produce super neodymium magnetsNeodymium countersunk magnet needs to confirm specific details, so please contact our staff.

    Neodymium Countersunk Ring Magnets

    In addition to large-scale products with regular shapes, sintered neodymium magnets are difficult to directly achieve the required shape and size due to the technical limitations of the magnetic field orientation molding process. head magnet. As a hard and brittle magnetic material, sintered neodymium magnet has been criticized for its machinability, so in the traditional processing technology, its processing technology can only use cutting, grinding and drilling. Hole machining processes include through holes and counterbores. The counterbore should be processed on the basis of the through hole. In order to ensure the concentricity of the through hole and the counterbore, it is necessary to accurately fix the workpiece during the machining of the counterbore.


    Electrification would not be possible without magnetic materials, as electricity is generated using generators, electricity is transmitted using transformers, electric machines are used in electric motors, and speakers are used in telephones, radios and televisions. Many instruments and meters must use the magnetic steel coil structure. The applications of magnets in daily life include loudspeakers, compasses, maglev trains, induction cookers, generators, etc.

    We sell all grades of neodymium magnets, custom shapes, sizes, and coatings.

    Magnetic Product Description:

    This neodymium magnetic disc has a diameter of 50mm and a height of 25mm. It has a magnetic flux reading of 4664 Gauss and a pull force of 68.22 kilos. 

    Uses For Our Strong Rare Earth Disc Magnets:

    Strong magnets, like this Rare Earth disc, project a powerful magnetic field that is capable of penetrating solid materials such as timber, glass or plastic. This ability has practical applications for tradespeople and engineers where strong magnets can be used to detect metal or become components in sensitive alarm systems and security locks.


    Ring magnet countersunk pulling force?

    The pulling force or holding strength of a ring magnet with a countersunk hole can vary widely based on several factors, including the magnet material, size, magnetization direction, countersink size, and the material of the surface to which it is attached. To provide an estimate of the pulling force, it's necessary to know the specific details of the magnet and its application.

    What polarity to choose for countersunk magnets?

    The choice of polarity for countersunk magnets depends on the specific application and the desired functionality you want to achieve. There are two main options: North (N) pole facing out or South (S) pole facing out. Here are considerations for each polarity:

    1. North (N) Pole Facing Out
    2. South (S) Pole Facing Out

    The choice of polarity will also depend on the overall design and functionality of your application. It's important to consider the interaction of the magnet with other magnets, materials, and the specific requirements of your project. In some cases, experimentation might be necessary to determine which polarity works best for your desired outcome.

    How to use countersunk neodymium magnets?

    Using countersunk neodymium magnets involves attaching them to surfaces while taking advantage of their countersunk hole design for a flush and secure installation. Here's a step-by-step guide on how to use countersunk neodymium magnets effectively:

    1. Select the Right Magnet
    2. Prepare the Surface
    3. Choose Polarity
    4. Positioning
    5. Screw Selection
    6. Attach the Magnet
    7. Tighten the Screw
    8. Testing
    9. Repeat as Needed
    10. Application-Specific Considerations
    11. Safety Precautions
