Product Description:
Bonded Neodymium Magnet is a unique type of multi-pole ring magnet
specially designed for high-precision applications. It is available
in a wide range of grades, including BN-4, BN-6, BN-8, BN-10, and
BN-12L, and can be packaged in various forms, such as carton boxes
and pallets. With a maximum operating temperature of 120°C-150°C
and magnetization directions of axial, radial, and multi-poles, the
Bonded Neodymium Magnet is an ideal choice for numerous
applications, particularly those requiring a 12-pole magnet.
