Grade N52 NdFeB – ultra-high magnetic energy for maximum holding force
Axially magnetized cylinder – North/South poles on flat circular faces
Ideal for motors, sensors, automation, medical, and high-efficiency assemblies
N52 neodymium cylinder magnets are ultra-high performance NdFeB magnets designed for applications requiring maximum magnetic strength in compact dimensions. Axially magnetized configuration means the North and South poles are located on the two flat circular faces of the cylinder.

Axial magnetization means the magnet is magnetized through its thickness, with the North pole on one flat face and the South pole on the opposite flat face.
Yes. N52 offers a higher maximum energy product (BHmax), meaning greater magnetic strength per volume compared to lower grades like N42 or N48.
Standard N52 magnets are rated up to 80°C. For higher temperature environments, H, SH, UH, EH or AH grade variants should be considered.
Yes. Diameter, thickness, tolerance, coating, magnetization direction, and packaging can be customized according to project requirements.
Yes. Industrial-grade NdFeB magnets can be supplied with RoHS compliance and proper packaging for export to Europe and North America.
