This is a strong power cylinder magnet, the specific size is 8mm in diameter, 20mm in thickness, the material is rare earth neodymium. It also called 8mm diameter cylinder magnet or permanent neodymium cylinder magnet. The surface coating is nickel and silvery white. The tolerance is ±0.05mm and the tolerance generally is negative tolerance. The direction of magnetizing is thickness, that means the strongest face is two round face. Custom can according to their needs, and then spliced the magnets into different lengths or shapes to use.
8x20mm neodymium cylinder magnet can be processed according to your needs through the middle hole into a hollow cylinder magnet, can also be radially magnetized, if you need special tolerances, temperature resistance requirements please explain, thank you!
