Neodymium Ring Magnet - (OD)20mm x (ID)10mm x (H)8mm | N45H | Epoxy Coating

This rare earth ring magnet has an outside diameter of 20mm, an inside diameter of 10mm and a thickness or height of 8mm. It has a pull force of 7.30 kg. It is identified by the AMF magnet part number 23013. Uses for our rare earth ring magnets:

All coatings impact the strength and holding ability of a magnet and Epoxy Coatings are no different. In some way compensating for the gap between surfaces that the coating creates, is the N45H Grade material of this ring, which is both high in magnetic energy and can also withstand operating temperatures up to 120° Celcius without failure or demagnetisation. As you would expect, the epoxy protects the Neodymium Ring from abrasive forces and protects it against moisture corrosion. These quality and performance-enhancing characteristics are reflected in the high unit price it attracts.
