Strong Rare-Earth Ring Magnets

Neodymium ring magnets are strong Rare-Earth magnets, circular in shape with a hollow center. Neodymium (also known as “Neo”, “NdFeb” or “NIB”) ring magnets are the most powerful magnets commercially available today with magnetic properties that far exceed those of other permanent magnet materials. Due to their high magnetic strength, neodymium ring magnets have replaced other magnetic materials in order to make a design smaller while achieving the same result.

Approximate Pull Information

The approximate pull info listed is for reference only. These values are calculated under the assumption that the magnet will be attached to a flat, ground 1/2″ thick mild steel plate. Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure. 

Manufacturing Methods

Our neodymium discs are sintered for optimal magnetic strength and axially magnetized (the magnetism direction is along the axis of the magnet from the north to the south poles). Common finishing options include uncoated, nickel (Ni-Cu-Ni) and gold (Ni-Cu-Ni-Au) plated coatings. 

Neodymium Ring Magnet Applications

NdFeB rod and cylinder magnets are often used in power generation equipment, high performance motors, consumer electronics, magnetic sensors, high-end audio equipment, surgical instruments and high-intensity separators for industrial, medical, aerospace, automotive and commercial industries as well as consumer use.

Custom Neodymium Ring Magnets

We can custom manufacturer neodymium ring magnets to fit your exact specifications, just send us a special request and we’ll help you determine the most cost effective solution for your specialty project.
