Magnetic Product Description:

This rare earth ring magnet has an outside diameter of 72mm, an inside diameter of 32.5mm and a height or thickness of 13mm. It has a pull force of 60kg. It is identified by the AMF magnet part number 23001.

Uses for our rare earth ring magnets:

Magnetic force can be used to influence or react to many mechanical operations and are part of devices like gauges and switches in many industrial and scientific processes. Ring Magnets can be located on shafts or lugs that allow them to interact with metallic or electromagnetic material in a consistent and predictable way. These interactions can indicate maximum or minimum tolerances or levels of operation or act as a warning device for impending faults or upcoming service requirements. In other cases, Ring magnets become part of the mechanism or machine itself by attracting or repelling metal or other magnetic material at a specified level of force. Traditional roles of detection, separation and purification are still applications that require the use of Ring magnets but they are usually employed in a more outcome-centric or job-specific manner. Highly accurate measuring devices and sensing equipment utilise Ring magnets in their operation. These devices can be found in the Aeronautical, Defence, Automotive and Aerospace industries where equipment that performs unreliably and inaccurately is totally unacceptable.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.

The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.

Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.

Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
