Neodymium Pot Magnet with Round Hole - 25mm x 8mm

Magnetic Product Description:

This rare earth pot magnet has an outside diameter of 25mm and an inside diameter of 5.5mm with an internal flange hole of 9mm. This round hole pot magnet has a thickness of 8mm, a pull force of 14kg and a weight of 23 grams. It is identified by the AMF magnet part number AMFYPB25.


Uses for our rare earth round hole pot magnets:

These Neodymium Pot Magnets have a round hole and are commonly attached using a bolt or integrated into an individual product design. The steel casing that protects the magnet from chipping and cracking also augments the magnetic field of the internal magnet. This also has the added benefit of creating a single-sided magnet that is stronger than a stand-alone magnet which can be highly beneficial in some application where there is a need to minimise any stray magnetic field. This magnet is popular with farmers, miners or anyone working with heavy machinery as its reliable holding force makes it perfect for attaching additional equipment such as electric drive systems, GPS tracking and guidance systems for mining vehicles and underground mining equipment.

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.
