Neodymium Ring Magnets Manufacturer,factory In China
Neodymium ring magnets are rare earth magnets that are round and ther is a hollow in the middle. The dimensions are expressed in terms of outside diameter, inside diameter and thickness.
Neodymium Ring magnets are magnetized in many ways. Radial magnetization, axial magnetization. Radial magnetization and how much magnetic pole magnetization.

Manufacturing Parameters for Neodymium Ring Magnets
Build-to-Print
All parameters are produced strictly according to customer drawings or confirmed technical specifications.
Outer diameter (OD)
The dimensional tolerance is controlled within ±0.05mm – ±0.10mm, ensuring high precision to meet the assembly requirements of various OEM projects.
Inner diameter (ID)
The tolerance is strictly controlled in line with customer specifications, generally ±0.05mm – ±0.10mm, to ensure a perfect fit with mating components (e.g., shafts, brackets) in the final product.
Thickness tolerance
The thickness of neodymium ring magnets is customizable, ensuring consistency in magnet thickness and avoiding assembly issues caused by dimensional deviations.
