Magnetic Product Description:
This rare earth ring magnet has an outside diameter of 20mm, an inside diameter of 4mm and a thickness of 12.7mm. It is identified by the AMF magnet part number 23007A
Uses for our rare earth ring magnets:
Neodymium Rings have similar properties to Disc magnets but produce less magnetic energy because of the missing void material. Unlike discs, they can sit on shafts or be located on pins and activate movement by attraction or repulsion of ferrous materials with little or zero friction impact during their operation. For this reason, they play an important role in manufacturing and industrial processing that is in continuous daily operation, often seven days a week. Permanent, predictable and virtually maintenance-free, they continually perform without the need for an external power supply and largely eliminate the production costs associated with mechanical failure due to fatigue. They provide an element of "'set and forget" confidence for manufacturers of delicate and expensive products that can be relied upon for very long periods.

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.
