A flat circular magnet with a thickness not exceeding the diameter and a through hole in the middle is called a ring magnet, or magnetic ring. It was called tube magnet if thickness exceed the diameter. The ring magnet can be fixed by mechanical connection. As a leading neodymium ring magnets factory in China, BeiLun Meank provides quality neodymium ring magnets for sale. Our neodymium magnets ring is divided into straight-hole magnetic rings and countersunk ring magnets. Compared with other shapes of magnets, ring circular neodymium magnets are easy to break due to external forces. The powerful ring magnets are specified by outer diameter, inner diameter and height, such as ring magnets OD20xID5xH5.

China Neodymium Ring Magnet Basic Info
Ring magnets are available for ferrite and rare earth, rare earth ring magnets are multifunctional and high-performance. Neodymium rare earth ring magnets (magnet neodymium rings) have been used since the 1980s. If you are looking for a very powerful ring magnet, NdFeB ring magnet is the most popular one for you. The north and south poles of the neodymium magnet rings can be magnetized on the opposite circular surface, or they can be magnetized radially so that the north pole is on one curved side and the south pole is on the other curved side. Most of rare earth ring magnets are supplied with axially magnetized. Neodymium rare earth ring magnets are very corrosive and need to be electroplated before use

The disadvantage of neodymium magnet rings is that they are very brittle and easy to crack. As one of the professional neodymium ring magnets manufacturers in China, BeiLun Meank do not recommend installing ring neodymium magnets with screws. It is safer and easier to use a countersunk ring magnet.

Strong Ring Neodymium Magnets
The neodymium ring magnets are known as the strongest (powerful) ones on the market. The minimum inner hole of our strong neodymium ring magnet can be 1mm regardless of size. Neodymium ring magnet (NdFeB magnet ring) N52 is the strongest ring magnet, which is much stronger than smco ring magnets. Most of neodymium ring magnets are axially magnetized. The holding force of a large neodymium ring magnet is as strong as 1000+ kg. You can stronger the neo ring magnets by encasing them with steel house.

Neodymium Ring Magnets Application
Due to its high permeability, neodymium ring magnets have become an ideal choice for many applications. Neodymium magnet rings can be used in scientific projects or experiments, medical applications, cabinets, water conditioning, loudspeakers and other commercial and industrial applications. Neodymium ring magnets for sale are used in many daily electrical appliances, such as vacuum cleaners, motors, generators, rotor shafts, etcWe can provide neodymium ring magnets of different sizes with several different coatings, such as nickel, zinc, epoxy resin or gold. As one of the leading neodymium ring magnets suppliers in China, we also provide waterproof magnetic rings with plastic and rubber coating.
