Neodymium Countersunk Ring Magnets

The flat and round shape NdFeB disc magnets with countersunk mounting hole are give the name of rare earth neodymium(NdFeB) countersunk ring magnets,which are special ring magnets and known as strong neodymium mountable magnets and screw on magnets. A strong neodymium countersunk ring magnet is expressed by out diameter(D) x inner diameter(d1/d2)x thickness(T).Neodymium countersunk ring magnets are widely used as magnetic holders in daily life.

Surface Treatment of Rare Earth Strong NdFeB Magnets with Countersunk Mounting Hole

Strong neodymium(NdFeB) countersunk ring magnets are easy to corrode, and their surface needs to be coated, generally including zinc plating, nickel, environmental protection zinc, environmental protection nickel, nickel copper-nickel, environmental protection nickel copper-nickel, epoxy coating, etc.

Magnetization Direction of Powerful & Strong Neodymium NdFeB Countersunk Ring Magnet

The magnetized direction of powerful neodymium(NdFeB) countersunk magnets generally divided into axially magnetized and diameter magnetized, which is determined according to the required working face. Please let us know which side is N or S-pole when you order strong neodymium countersunk ring magnets.

Custom Strong Neodymium(NdFeB) Disc Magnets Countersunk Hole

neodymium magnets with screw holes are non-standard magnet rings, due to the good machinability of sintered Nd-Fe-B material, strong magnets with screw holes can be customized into neodymium(NdFeB) countersunk ring magnets in different sizes, mold is not necessary for customizing strong neodymium countersunk magnets. We can make strong tiny and large neodymium countersunk magnets for any quantity.
