Ring Magnets - Neodymium & Samarium Cobalt

55 products

Showing 1 - 24 of 55 products

Ring magnets offer a unique geometry that’s ideal for applications requiring a central hole for mounting, rotation, or sensing alignment. At SuperMagnetMan, we stock both Neodymium (NdFeB) and Samarium Cobalt (SmCo) ring magnets in a wide range of inner/outer diameters, thicknesses, and coatings.

Neodymium ring magnets are perfect when maximum magnetic strength is needed in compact designs—commonly used in motors, robotics, and sensors. For applications exposed to high temperatures or corrosive environments, SmCo ring magnets provide excellent stability and long-term durability.

We offer a variety of standard sizes ready to ship, with custom sizing and magnetization options available to meet your specific application requirements.

Looking for something custom or unsure what works best for your application? Contact us to speak to one of our experts or request a quote.
