Leyuan Group Co., Ltd. is an experienced magnetic products manufacturer. We focus on the production of magnetic product related to permanent magnets.
These neodymium magnets with countersunk holes/neodymium disc countersunk hole magnets have only one surface that has strong magnetism; the other surface of the strong magnets with hole just has very weak magnetism.
Leyuan round countersunk magnets have excellent holding forces thanks to the use of anisotropic neodymium (NdFeB) magnets. The maximum working temperature of these types is up to 80°C, and the steel body is galvanized. These types are used in applications where high holding forces and small dimensions are required.
Application: magnet source round base magnet can be inserted into different instruments, machines, and tools. These countersunk rare earth magnets can be used effectively as auxiliary instruments during transport, clamping, mounting, lifting, welding, separation, etc. The best holding force is reached at full contact of the magnetic face with the ground ferromagnetic surface. Force is vertical to the base (air gap = 0 mm). Small cracks on the neodymium round base magnet or steel pot do not have any influence as to the functionality, lifetime, and holding force of the pot magnet.

The Advantages of Pot Magnets With Bore
Pot magnets can be inserted into different instruments, machines, tools. Can be used as auxiliary instruments during transport, clamping, mounting, lifting, welding, separation, etc. The best holding force is reached at full contact of the magnetic face with the ground ferromagnetic surface, force is vertical to the base (air gap = 0 mm). Small cracks on the magnet or steel pot do not have any influence to the functionality, lifetime and holding force of the pot magnet.
