Rare Earth NdFeB Neodymium Ring Magnets From micro to large neodymium ring magnets, we quote to your drawing and application: size (OD/ID/H), grade + temperature grade, magnetization (axial/radial/diametric), and coating—so you can validate performance in your real steel and air-gap conditions. OD (1.5–300 mm), ID (0.4–250 mm), Thickness (0.3–120 mm) Grades: N35–N55 + H/M/SH/EH/AH Magnetization: Axial / Radial / Diametric Coatings: NiCuNi / Zn / Epoxy (as needed) Rare earth neodymium ring magnets (NdFeB)—often called magnet rings—are donut-shaped permanent magnets with a center hole for repeatable mounting on shafts, rods, and fasteners. In rotating builds (motors, encoders, speakers, couplings), that repeatable alignment is usually the difference between “works on paper” and stable performance over time—so grade and magnetization need to match the real assembly. A quick production lesson: grade is a material spec, not a [...]

Grade N55 Neodymium Magnets Higher strength – 5–6% stronger performance than N52 magnets. Precision use – Ideal for magnetic sensors and magnetic switches. Miniature fit – Best choice for tiny magnets and small robots. Durable design – Resistant to demagnetization, heat; coating protection required. We are proud to offer N55 Super Magnets to our customers. This is not because all magnet factories can produce. Rather, it is smaller in size and stronger in magnetic force than N52. Its performance is 5%-6% higher than that of N52 magnet. For precision applications such as magnetic sensors, magnetic switches, etc., N55 is the best choice. Due to its strong magnetic field, the N55 is ideal for making tiny magnets and tiny robots. Like other N-series neodymium magnets, N55 magnets are resistant to demagnetization and heat. And coating is [...]

Grade N54 Neodymium Magnets N54 neodymium magnets are the industrial grade of NdFeB magnets with the highest magnetic energy product ((BH)max) currently available for mass production. According to the Chinese national standard (BG/T 13560-2017, Sintered NdFeB permanent magnets), N54 has the highest maximum energy product ((BH)max) of 51 to 55 MGOe and remanence (Br) of 1.45 to 14.9 kG. Since there is no unified standard internationally, manufacturers and customers in some regions also use “N55 neodymium magnets” as the name. Definition of N54 magnet. I know that some customers are not very good at reading the “performance ID card” of magnets. Usually the grade of magnets is written in the format of: “First letter + number + suffix letter” First letter: indicates the material of the magnet, for example: “N” stands for neodymium, “C” stands [...]

Grade N52 Neodymium Magnets Superior strength – Grade N52 magnets with high (BH)max and deep magnetic field. Application fit – Ideal for strong holding, motors; weaker grades suit low strength.
