Magnetic couplings

Contactless magnetic couplings in demanding conditions

Magnetic couplings are non-contact devices used to transfer torque from one shaft to another through a magnetic field, without any physical connection. 

Are there components in your transport or production line that are exposed to demanding conditions, such as high temperatures, extreme pressure, a vacuum, or the handling of liquids and chemicals? Then magnetic couplings are the ideal solution for your application.

Our industrial magnetic coupling systems use strong permanent magnetic couplings, such as neodymium or samarium cobalt, to ensure safe and efficient operation, even in harsh environments. For applications that demand more power, we offer high torque magnetic couplings designed for maximum performance and reliability.

This contactless technology allows you to transmit rotational force without requiring a shaft or wall penetration. As a result, maintenance-free magnetic couplings come with a range of valuable benefits:
✓ No risk of leakage
✓ No loss of pressure
✓ No mechanical wear

And with the right choice of magnets, they can withstand extremely high temperatures.

Is a magnetic coupling the right solution for your process? We’d be happy to explore the possibilities with you.

Why use magnetic couplings?

Magnetic couplings are a smart and future-proof alternative to traditional mechanical connections – especially when reliability, safety, and minimal maintenance are critical to your process. Here’s why more and more industries choose magnetic couplings:

  • No physical contact between driving and driven side
  • No seals required, so no leakage risk
  • Low maintenance or even fully maintenance-free
  • Resistant to high temperatures with the right magnet material
  • Reliable operation in vacuum or under pressure
  • Compact and durable design

Depending on the application, we supply permanent magnetic couplings using high-quality materials such as neodymium or samarium cobalt magnetic couplings. Samarium cobalt is particularly well-suited for extreme conditions due to its excellent resistance to corrosion and demagnetization.

Custom magnetic coupling design

Every production environment has its own challenges – whether it’s torque requirements, extreme temperatures, chemical exposure, or space limitations. That’s why we offer custom magnetic coupling design, engineered specifically for your application.

As an experienced magnetic couplings supplier, we develop solutions that go far beyond off-the-shelf components. Together with your team, our engineers design, prototype and assemble couplings that integrate seamlessly into your system, both mechanically and magnetically. We take into account all critical design factors, including:

  • Torque range, alignment and efficiency
  • Chemical resistance and corrosion protection
  • Operating conditions such as vacuum or overpressure
  • Risk of demagnetization and need for magnetic shielding
  • Material compatibility, e.g. stainless steel housings
  • Installation constraints and temperature stability

Depending on your needs, we use high torque magnetic couplings made from neodymium or samarium cobalt. Especially in extreme environments, samarium cobalt magnetic couplings offer excellent resistance to corrosion and demagnetization, ensuring long-term reliability and safety.

We also support rapid prototyping and short development cycles, so you can move quickly from idea to tested product.
