Magnet Business

We develop, manufacture, and sell "magnetic gears," which transmit power without contact.

Magnetic gears solve the many problems that occur in conventional transmission mechanisms -- friction and particle generation, grease-up, noise and vibration, and risk of injury during maintenance -- achieving particle-free operation, maintenance-free design, low noise and vibration, and safety.
