What Magnets Are Suitable For Industrial Magnetic Couplings And Magnetic Gear Units?

Magnetic couplings and magnetic gears adopt non‑contact magnetic transmission to isolate vibration, avoid leakage and reduce mechanical wear, which are widely used in pumps, mixers and industrial transmission equipment. Selecting proper permanent magnets directly decides service life and stable running of whole system.

Rectangular N38H sintered neodymium magnet is one typical solution for such equipment. This grade delivers high magnetic energy product with typical working temperature up to 120℃. It can withstand continuous operating temperature rise generated during torque transmission, effectively preventing irreversible demagnetization under normal load. Nickel coating is commonly applied for anti‑corrosion performance against humid industrial environment.

Many buyers only focus on magnetic strength but ignore temperature resistance. Low‑grade magnets will lose partial magnetism under continuous heat, leading to equipment failure. Apart from N38H, engineers may select SH or UH series for higher‑temperature heavy‑duty working scenarios according to real‑world thermal data.
