SDM High Strong N52 Cylinder Permanent Magnet Industrial Rod Neodymium Magnet


N52 Cylinder Permanent Magnet Industrial Rod Neodymium Magnets are among the strongest magnets available today, made from an alloy of neodymium, iron, and boron (NdFeB). The "N52" grade denotes one of the highest available magnetic grades, indicating a very high magnetic field strength. These cylindrical rod magnets are specifically designed for a wide range of industrial applications due to their powerful magnetic properties and versatility. Here are their key functions and features:


  1. Holding and Lifting: Thanks to their strong magnetic field, N52 cylinder magnets are widely used in holding and lifting applications where a compact but powerful magnet is required.

  2. Sensors and Actuators: The precise and strong magnetic field of N52 magnets makes them ideal for use in sensors and actuators within various industrial equipment.

  3. Magnetic Separation: These magnets can be used in magnetic separators to remove ferromagnetic materials from a mixture of compounds.

  4. Electric Motors and Generators: N52 cylinder magnets are crucial components in the design of high-performance electric motors and generators due to their ability to produce a high magnetic field in a small size.

  5. Couplings and Bearings: Magnetic couplings and bearings often use N52 magnets for contactless transmission of force, reducing wear and increasing efficiency.


  1. High Magnetic Strength: N52 magnets provide one of the highest levels of magnetic field strength available in neodymium magnets.

  2. Compact Size with High Force: Despite their small size, these magnets can generate an immense amount of magnetic force, making them suitable for applications where space is limited.

  3. Corrosion Resistance: With appropriate coatings such as nickel, zinc, or epoxy, N52 cylinder magnets can resist corrosion, extending their lifespan in harsh environments.

  4. Versatility: These magnets can be utilized in a vast array of applications across different industries due to their strength and durability.

  5. Temperature Sensitivity: While powerful, N52 magnets have a relatively lower maximum operating temperature compared to lower grade neodymium magnets. Special care needs to be taken in applications involving high temperatures.

  6. Cost-Effectiveness: Given their strong magnetic properties, N52 neodymium magnets offer a cost-effective solution for many industrial applications requiring intense magnetic fields.

It's important to handle N52 cylinder neodymium magnets with care due to their powerful magnetic pull, which can cause injury or damage if not managed properly. Additionally, their performance can degrade if exposed to temperatures above their maximum operating limit, typically around 80°C (176°F) for standard N52 magnets.
