Product Description:

This rare earth ring magnet has an outside diameter of 19mm, an inside diameter of 8mm and a thickness of 4mm. It is identified by AMF Magnets part number 23008.

Uses for our rare earth ring magnets:

In the rail industry, neodymium ring magnets are used extensively within wheel assemblies, braking systems, and traction components. Magnets are also used extensively in the lifting and depot equipment in the rail workshops. Ring magnets used on an axle or rod with stationary and moving parts are used to help regulate movement which helps ensure the smooth operation of rail travel.

Smooth operation also reduces wear and tear on the wheels and brakes and rail tracks, as well as reduces noise. The known pull force of magnets allows engineers to determine release points within the system to control the transfer of force or reduce the amount of force being directly transferred through the various assemblies.

Magnets can also be used to reduce the wild forces that swaying carriages moving at speed are able to generate. Magnetic engagement between the individual carriages allows train engineers and builders to determine at which point a carriage should release. Magnets have always, and still are, helping our trains run smoother, safer and faster for longer!

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.
