Products Overview

Neodymium Rings Features

Neodymium ring magnets are being designed into a new generation of motors, generators, hydraulic cylinders, pumps & sensors. They also remain popular in high-end loud speakers & high-intensity separators.

Features include:

• Neodymium magnets are the most powerful commercially produced magnets.

• Neodymium magnets are hard and brittle and may chip or break if dropped.

• Adams Neodymium ring magnets are magnetized through the thickness.

• Uncoated neodymium magnets may corrode in humid conditions.

• Operating temperatures vary among material grades. For a comparison of neodymium material grades, please visit our chart of material properties.

Product Specifications

Dimensions are listed in inches. All rings listed are supplied magnetized through the thickness.  Additional sizes, plating options, magnetization methods and grade choices are also available upon request and may be on hand from stock.

Gluing Magnets

Neodymium magnets are often assembled into products using strong adhesives such as Loctite 325. Make sure that all contact surfaces are clean and dry prior to bonding.

Handle with care!

Please use caution when handling magnetized neodymium magnets, their exceptional magnetic force may cause them to attract to metal (or to each other) so strongly that fingers in their path could prove painful.
