Neodymium Ring Magnets

Neodymium Ring Magnets (NdFeB Ring Magnets) are engineered with a central hole to deliver concentrated, high-strength magnetic fields in a compact and versatile form factor. As a core component in modern precision devices, our ring magnets combine the unparalleled strength of rare earth neodymium with specialized designs to meet exacting requirements for efficiency, size, and reliability in dynamic applications.

Core  Advantages: Precision Power in a Ring

1. Optimized Magnetic Circuit Design: The ring shape with a central hole allows for unique axial or diametric magnetization, enabling more efficient and focused magnetic flux paths for motors, sensors, and audio systems, often leading to enhanced performance in compact spaces.

2. Superior Strength-to-Size Ratio: Made from high-grade NdFeB material (including grades like N35 to N52), these magnets provide one of the strongest magnetic outputs commercially available for their size, allowing for miniaturization and weight reduction in end products.

3. Enhanced Mechanical & Environmental Fit: The central bore facilitates easy integration, mounting, and assembly onto shafts or components. Available with various protective coatings (Ni, Zn, Epoxy), they offer improved resistance to corrosion and wear for long-term durability.

Key Features

• Comprehensive Grade Selection: We offer a range of magnetic grades to suit different needs, from cost-effective standard grades to high-performance N52 and high-temperature series (e.g., SH, UH), balancing pull force, coercivity, and thermal stability.

• Precision Dimensional Customization: Rings can be manufactured to precise specifications, including inner/outer diameter, thickness, and tolerance, to fit seamlessly into your design. Diametric magnetization for sensor applications is a key specialty.

• Application-Ready Solutions: We provide magnets tailored for specific industries, whether it's requiring ultra-strong N52 magnets for high-torque motors, or precisely magnetized rings for speakers and microphones in audio equipment.

Typical Application 

• Motors & Actuators: Critical in brushless DC motors, servo motors, stepper motors, and linear actuators for automotive, robotics, and automation, providing efficient torque and compact design.

• Electroacoustic Devices: Widely used in speakers, headphones, microphones, and acoustic transducers to deliver clear, powerful sound with high sensitivity.

• Sensors & Instrumentation: Ideal for position sensors, encoders, Hall-effect sensors, and medical imaging devices where precise and stable magnetic fields are crucial.

• Industrial & Consumer Electronics: Employed in magnetic couplings, holding fixtures, smartphone vibration modules, and smart home devices.
