Neodymium pot magnets with countersunk holes are versatile magnetic assemblies commonly used in applications where a flush and secure mounting is required. These magnets feature a neodymium magnet encased within a steel pot or casing, which enhances the magnetic strength and provides protection against damage.
The magnetic line of the neodymium countersunk magnets is concentrated on the working surface, and there is almost no magnetic force on the non working surface, they are seemed as single-sided magnets.
The powerful countersunk magnets with steel housed are more durable and mountable.
Neodymium countersunk magnets which encased in steel cups are plated with Nickel-Copper-Nickel (Ni-Cu-Ni) for maximum protection against rust.
The approximate vertical pull force value of neodymium countersunk pot/cup magnets are for reference only. Because the values are measured under ideal conditions when the magnet is connected to a 1/2" thick flat ground mild steel plate. Corrosion, rough surfaces and some other conditions in practical use can significantly reduce the vertical pull force. Please test the pull force under actual working conditions. For critical applications, it is recommended to appropriately underestimate the magnetic force according to potential adverse conditions.
In addition to the standard models neodymium countersunk pot magnets for sale, we can also customize neodymium countersunk cup magnets according to your specific specifications. For questions about your professional project, please contact us or send us a quotation request.
