Rings
Ring magnets are disc-shaped neodymium magnets with a hole through the center, so they slide over a bolt, dowel, rod or shaft, or mount with a screw. They're used in workshops, motors and sensors, science demonstrations, crafts and anywhere a magnet needs to stay centered on a post.
Sizes run from tiny 4 mm rings up to a 6 inch ring, in metric sizes from 4 to 38 mm and inch sizes from 1/4 to 6 inches across, with rated pull forces from under 1 pound to over 400 pounds. Most are grade N48 neodymium magnetized through the thickness. We also stock diametric rings magnetized across the diameter, longer tubes, a samarium cobalt (SmCo30) ring for high-temperature use, and economical ceramic (C11) rings.
Need a ring that screws flush to a surface? See our countersunk magnets. Every size includes volume pricing.
Neodymium magnets are intended for adults 18 and older. Keep small magnets away from children and pets.
