Neodymium Ring - 22 mm x 4.5 mm x 10 mm | Countersunk
Product code: 23004
Neodymium Ring - 22 mm x 4.5 mm x 10 mm | Countersunk
Product Description:
This neodymium rare earth ring magnet measures 22 mm (OD) x 4.5 mm (ID) x 10 mm (T).
It has a pull force of 12.6 kg. GRADE N38.
Uses for ring magnets:
Strong ring magnets like these with a pull force of 12.6 kg are used to help hold and or regulate movement, release at a predetermined pull force, and or re-engage or hold again, moving parts. Sometimes threaded onto a spool or axle or rod, ring magnets, as well as regulating movement of nearby moving parts, also contain or compress moving parts that might otherwise drift from their allotted position and damage or reduce mechanical efficiency. The amount of magnetic force needs to be such that it can contain or compress the moving parts negating drift, but not so strong as to suppress movement necessary for efficient mechanical function. The known pull force or magnetic strength of a particular magnet allows engineers and others to design sophisticated equipment that is reliable and durable.
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.
