Ring Magnet Dimensions

Magnetic Product Description:

This neodymium magnetic ring has an outer diameter of 76.2mm, an inner diameter of 25.4mm and the height of 12.7mm. It is identified by the AMF magnet part number R-OD76.2H12.7ID25.4-N35.

Uses for our Rare Earth ring magnets:

Ring-shaped magnets made from Rare Earth materials, such as Neodymium, are extremely strong and versatile. They have wide-ranging uses in both complex industrial processes and common household applications. The centre hole can be used to locate the magnet in a precise position and then become an important component in manufacturing processes. A strong Ring magnet placed on a shaft or a locating pin made from a non-ferromagnetic material can ensure the magnet is either secured in place or, in some applications, able to move along the shaft in response to the presence of a ferrous material or an electromagnetic field. In many manufacturing or metal detecting systems the magnet will activate a warning, interrupt the manufacturing process or initiate the next phase of production.
This strong Neodymium Ring magnet also shares the exact imperial measurements of 3x1x1/2 inches and is interchangeable with applications that require these dimensions.

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.
