Ring Neodymium Magnets, Nickel Plated Hollow Round NdFeB Ring Magnets for Motor Sensor Industry

Nickel/Zinc/Epoxy Coating | N35-N52 SH Grade | Custom Magnetization & Size
      Ring neodymium magnet is a special hollow circular rare earth magnet, customized with center through hole structure, which is irreplaceable for shaft matching, bolt assembly, magnetic coupling, sensor induction and permanent magnet motor manufacturing. Different from solid disc magnets, the hollow ring structure allows shaft penetration, bolt locking and nested installation, greatly simplifying mechanical assembly procedure for industrial engineers.
     Made of high-purity sintered NdFeB raw material, our hollow ring magnets deliver ultra-high remanence and stable coercivity. We provide complete magnet grade selection: conventional N35-N52 normal temperature grade for DIY craft, fixture holding and household electronics; professional SH/EH/TH high temperature resistant grade for long-running BLDC motors, automotive parts and industrial automation equipment, which will not demagnetize under continuous high-temperature working environment.
Multiple surface protective coatings meet different usage scenarios. Triple nickel plating is the most popular option, featuring wear-resistant, anti-oxidation and bright surface for general industrial use. Zinc coating offers cost-effective anti-rust performance for indoor assembly. Full epoxy coating provides waterproof and salt-spray resistance, ideal for outdoor, coastal and humid mechanical equipment. All edges are finely chamfered to avoid crack chipping during installation and nested assembly.
     Support diversified magnetization customization: axial magnetization, radial magnetization, multi-pole segmentation magnetization to match motor rotor, magnetic sensor and magnetic coupling design. All common inner and outer diameter ring magnets are in stock, including hot sale size: 20x10x5mm, 30x15x8mm, 40x20x10mm. We accept OEM custom outer diameter, inner hole, thickness and tolerance per customer mechanical drawings.
      Wide industry application: permanent magnet motor rotor, magnetic coupling connector, speed sensor component, magnetic induction switch, bolt fixed magnetic fixture, audio speaker part, DIY magnetic assembly, automotive electronic parts, wind power equipment and medical magnetic devices. Support sample trial order, small batch customization and factory bulk wholesale, strict dimension and magnetic flux inspection before delivery
