China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Because different customers have different requirements for ring magnets in terms of magnetic strength, temperature resistance, size, etc., so in many cases they need to be customized. In addition to choosing the right material, ring magnets can be customized in different types of shapes.
1、Standard ring magnets
Standard ring is the most common ring magnet shape, with uniform inner and outer diameters, size processing range of about 3mm-230mm.
The picture below shows a standard nickel-plated radial ring neodymium magnet with an outer diameter of 20mm, a hole of 15mm and a thickness of 3mm.
2、Ring magnets with holes
Punch holes in the plane or side of the ring magnet, the number of holes can be 1 or more, welcome to send drawings for evaluation.

3、Ring magnets with slots
Similar to magnets with holes, the end or side of the ring magnet is slotted, and the width and depth of the slot can be processed according to your actual needs.
4, Convex ring magnets
Like a convex circular magnet, a convex ring magnet only has a hole in the middle, as shown in the reference sample convex step round ring strong ndfeb magnet with hole in center.
5. Runway ring magnets
Runway ring magnets are a special type of ring magnet that is similar in shape to a runway, i.e., semi-circular at both ends and a straight section in the middle portion, with a hole in the center that can be either a standard ring or countersunk.
