8 Pole Neodymium Magnet Ring Customized Size +/-0.05mm Grade BN-10
Product Description:
Bonded Neodymium Magnet is an injection bonded magnet made of
Neodymium Iron Boron (NdFeB) material. It is widely used in motors,
such as spinder motor, stepping motor, synchronous motor, DC motor,
brushless motor and more. It is available in various grades,
including BN-6, BN-8, BN-10 and so on. With its excellent
temperature resistance, the maximum operating temperature of Bonded
Neodymium Magnet can be up to 120°C, and it is also coated with
epoxy or parylene to prevent corrosion and temperature damage.
Bonded Neodymium Magnet is mainly used for high speed motors, as
its high magnetic force and strong stability make it ideal for such
applications. With its advanced injection bonded technology, Bonded
Neodymium Magnet can offer high performance in different working
environments.

Packing and Shipping:
Packaging and Shipping of Bonded Neodymium Magnet
Bonded neodymium magnets are packaged and shipped in boxes with
multiple layers of protective materials such as foam and bubble
wrap. The boxes are then sealed and placed in a larger box with
additional padding. The magnets are also labeled with a warning
label to alert handlers of the powerful nature of neodymium
magnets.
When shipping, bonded neodymium magnets should be shipped by a
trusted, insured shipping company. The box with the magnets should
be clearly labeled with the contents. The package should also be
marked as "Fragile" and "This Side Up" to ensure that it is not
mishandled during transit.
