Magnetic Product Description:

This rare earth disc has a diameter of 101.6mm and a height of 25.4mm or one inch. It has a magnetic flux reading of 2817 Gauss and a pull force of  237.9kg. It is identified by the AMF magnet part number 20000.

Uses for our rare earth disc magnets:

With a pull force of 237.9 kg, it’s no wonder these neodymium disc magnets measuring 101.6mm in diameter sell well to companies whose job it is to lift heavy objects.

As well as cranes, hoists and winches in workplaces and in the field, these Neodymium Disc magnets are also to be found in homes, hospitals and aged care facilities. In fact, anywhere heavy lifting is involved.

Lifting heavy objects can inflict serious injury if precautions are not undertaken. These powerful magnets are engaged in a wide variety of machines and lifting equipment. These devices help reduce the inherent risks when lifting or elevating heavy or awkward objects. This magnetic method of lifting also reduces the risk of slippage, twisting or failure more likely with tying-type engagements like chains, straps or ropes. These old technologies require getting underneath the heavy object before you even start the lift. Magnetic force can be applied to the top or sides of an object so it can be lifted or pulled away.

Magnetic force and engagement to lift heavy items can provide more security and personal safety before, during, and after the lifting exercise, than more conventional methods. There are many lifting devices on the market utilizing these powerful magnets to ease the burden of lifting in a safe and responsible way.

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.
