Overview - Neodymium NdFeb Ring Magnets

Neodymium (rare earth) NdFeB ring magnets / NdFeB countersunk ring magnets / NdFeB counterbore ring magnets

Neodymium ring magnets are high-strength permanent magnets manufactured from neodymium-iron-boron (NdFeB), offering exceptional magnetic performance in a ring or hollow disc shape. This unique geometry provides a central aperture that enables easy mounting, fastening, or integration with mechanical components, making these magnets ideal for a wide range of industrial, engineering, workshop, prototyping, and DIY applications.

The ring shape concentrates the magnetic field around the periphery while allowing components such as bolts, shafts, or fasteners to pass through the central hole, combining magnetic attraction with mechanical functionality. Neodymium magnet material is known for its very high energy product, meaning these ring magnets deliver powerful holding force relative to size, even in compact formats. Protective finishes are often applied to enhance corrosion resistance and durability, ensuring reliable performance in diverse environments.

Neodymium ring magnets are versatile magnetic solutions for users requiring strong, compact, and functional magnets that integrate both magnetic and mechanical needs.


Typical Applications

Neodymium Ring Magnets are commonly used for:

  • Magnetic couplings and fastenings in mechanical assemblies

  • Sensor and encoder mounting where central apertures support shaft alignment

  • Magnetic fixtures and positioning tools

  • DIY and prototyping projects requiring magnetic attachment with a central mounting point

  • Holding, retrieving, and aligning ferrous components around a central axis

Their combination of strong magnetic force and functional ring shape makes these magnets suitable for technical, industrial, and creative projects.


Why Choose Neodymium Ring Magnets

Neodymium ring magnets deliver exceptional magnetic strength, compact versatility, and mechanical adaptability in a single solution. The central aperture enhances mounting flexibility, allowing them to be easily fixed or aligned with fasteners, shafts, or hardware while providing powerful magnetic attraction around the perimeter. These magnets are a practical choice for professionals, engineers, makers, and DIY enthusiasts who need high-performance magnets with integrated mounting capability.


Key Benefits

  • High magnetic strength – powerful holding force in a compact ring form

  • Functional ring shape – central aperture enables versatile mounting and integration

  • Durable design – robust magnetic performance with corrosion-resistant finish

  • Versatile applications – industrial, mechanical, DIY, and prototyping use

  • Compact and adaptable – ideal where space and functionality matter

We also offer Ferrite ring magnets.
