Multi Pole Magnet Ring For Stepping Motor
Product Description:
Bonded Neodymium Magnet is a kind of injection bonded magnet made
from NdFeB alloy powder. It is featured by high magnetic
performance, stable magnetic properties, and strong corrosion
resistance. The multi pole ring shape provides maximum magnetic
holding force in an axial direction. It is available in a range of
sizes and shapes, and customized services are also available.
Besides, it offers a variety of coating options, including epoxy,
nickel, parylene, etc. for various applications. The packaging is
usually carton box, pallet, etc. Bonded Neodymium Magnet can be
widely used in spinder motor, stepping motor, synchronous motor, DC
motor, brushless motor, etc.

Packing and Shipping:
Packaging and Shipping of Bonded Neodymium Magnet
Bonded neodymium magnets are prone to cracking and chipping, so it
is important to take proper care while packaging and shipping them.
We recommend the following packaging and shipping protocols:
- Place the magnet into a plastic bag to shield it from any external
damage.
- Surround the plastic bag with foam to provide additional
cushioning.
- Place the bagged magnet into a box of appropriate size.
- Fill any remaining space in the box with packing peanuts or other
cushioning material.
- Securely close the box with packing tape.
- Label the box with the correct shipping address and handling
instructions.
- Ship the box via a reliable courier.
