Rod shape magnets are long circular magnets where the length is equal to or greater than the diameter.
Neodymium rod magnets are typically used in medical, sensor, read switches, meters, and holding applications. Neodymium rod magnets can be magnetized through the length or across the diameter. The shape of a neodymium rod magnet produces a magnetic field with a longer reach.

Engineering drawing is important and necessary for rod shaped magnets. To avoid any misunderstanding of the dimensions and positions, please provide a clear drawing with detailed specifications, tolerance and additional requirements if any.
We list some drawings of common types of Neodymium magnet rod as follows for your information.
Surface treatmen
For iron component (about 66%), it is easy disadvantages oxidizing power is strong rust there often (neodymium magnet) Nd-Fe-B sintered magnet. Surface treatment that a mandatory essential to prevent it, there is a method using various materials in it. To determine the material of plating depending on the environment used is neodymium.
