20mm Diameter Ring Magnets
All the ring magnets in this section have an outer diameter of 20mm but each has a different inner diameter making them entirely different in their applications. Below, you can browse our ferrite ring magnets that are resistant to corrosion and high temperatures and offer great value, our super high-performance neodymium ring magnets and our deep cylindrical magnets with pre-drilled central holes.
