China alibaba neodymium ndfeb ring dc motor magnet

China alibaba neodymium ndfeb ring dc motor magnet   Product description     Product info       Neodymium (or “Neo”) magnets are a type of Rare Earth Magnet, with the highest magnetic properties- the most powerful magnets available today. While extremely powerful, Neo magnets are more affordable for non-technical applications such as holding, magnetic jewelry, clasps, etc….

By Sea: As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton. (Detailed package quantity should be made upon the real products) 2. By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.       Shipping      Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
a: The weight is under 40Kgs, we recommend to send them in shielding boxes to you by Express.
b: The weight is between 40Kgs-100Kgs, it can be sent by Express or Air.
c: The weight is over 100Kgs, we recommend to send them by Ocean.   Payment terms   FAQ: FAQ     1: What is normal dimension of your products? All magnets are customized. 2. What information do I need to supply when I have a inquiry? If you have any inquiry, please kindly advise the following items: a. Dimensions or drawing with tolerances. b. Material grade or magnetic properties.
c. Magnetic direction.
