Magnetic Couplings

For reliable, long-term protection against frequent overloads, our magnetic couplings are the ideal choice. They operate completely wear-free, ensuring fatigue strength and maintenance-free performance. The simple clamping hub connection and quick overload torque adjustment—achieved by varying the insertion depth of the inner rotor into the outer rotor—enable fast and hassle-free use. Two operating principles are available: the permanent magnetic coupling, which exhibits a bucking effect under overload, and the hysteresis coupling, which smoothly slips similar to a sliding coupling.

PMK

The permanent magnetic coupling features a bucking characteristic under overload conditions, ensuring reliable performance. Designed for high torque applications, its specialized magnet orientation also makes it ideal for indexing operations.

HMK

Hysteresis couplings provide smooth, slip-resistant performance under overload conditions. Due to the use of hysteresis material, they transmit lower torques compared to our "PMK" series and generate thermal energy while slipping.

HSM

Under overload conditions, the hysteresis magnetic coupling smoothly slips to protect the system. The laser-engraved scale allows for precise and easy adjustment of the overload torque.

HLM

Under overload conditions, the hysteresis magnetic coupling smoothly slips to protect the system. The laser-engraved scale enables precise and easy adjustment of the overload torque. This version is typically made of stainless steel for durability and reliability.

AMK

Magnetic disc couplings transmit torque contact-free and without wear, ensuring reliable performance through housings while providing overload protection.

HMVX

Hysteresis couplings provide smooth, slip-resistant performance under overload conditions. This new series features an internal bearing support and a length-adjustable design, allowing for easy overload torque adjustment. Additionally, the integrated Oldham-style coupling compensates for potential shaft misalignment.
