Frequently Asked Questions

Ring magnets are commonly used in motors, couplings, sensors, and magnetic assemblies.

Neodymium magnets are the strongest and most cost-effective but require protective coatings and have lower heat resistance. Samarium Cobalt magnets are slightly less powerful but offer superior temperature stability, natural corrosion resistance, and long-term durability in harsh environments.

Ring magnets provide smooth integration in shafts, encoders, and motion systems. Their centered alignment makes them ideal for testing rotational prototypes.

We provide a wide range of coatings to match different applications. Common options include nickel, gold, and epoxy. Nickel is the standard for durability, gold is our biocompatible coating and preferred for medical use, and epoxy adds strong chemical resistance. Additional specialty coatings are also available depending on your requirements.

Yes. Through our engineering division, SM Magnetics, we can design and manufacture custom sizes, magnetization directions, and specialized coatings. You can either submit a custom request form or contact us directly to speak with our experts.
