Magnetic Co-Axial Couplings
Magnetic Co-Axial Couplings
Magnetic co-axial couplings provide contactless torque transmission, typically used in applications requiring seal-less operation to prevent leakage of corrosive, toxic, or flammable liquids. The torque is transmitted magnetically between two hubs, which can be separated by air or a non-magnetic barrier, ensuring complete isolation.
Specifications
The co-axial coupling consists of three main components: the inner hub, the outer hub, and an optional containment barrier. Both hubs are equipped with rare earth magnets, sealed in stainless steel to protect against damage and corrosion. These couplings are ideal for applications like magnetic mixers, where the driven hub is separated from the driver hub.
Key Features
- Eliminates the need for rotating seals.
- No wearing parts, ensuring longevity.
- Synchronous design with no slip at any speed.
- No physical contact between driving and driven parts.
- Safe for use up to 140°C, with high-temperature designs available.
- Custom designs available upon request.
Technical Specifications
Various models are available, each with specific rated torque, slip torque, maximum speed, and weight. For example:
- MTC-0.06: Rated Torque 0.06 Nm, Max Speed 44,000 RPM, Weight 0.1 kg.
- MTC-0.1: Rated Torque 0.1 Nm, Max Speed 44,000 RPM, Weight 0.1 kg.
- MTC-0.3: Rated Torque 0.3 Nm, Max Speed 26,000 RPM, Weight 0.3 kg.
- MTC-1: Rated Torque 1 Nm, Max Speed 22,000 RPM, Weight 0.8 kg.
- MTC-3: Rated Torque 3 Nm, Max Speed 18,000 RPM, Weight 1 kg.
- MTC-10: Rated Torque 10 Nm, Max Speed 13,000 RPM, Weight 2.5 kg.
Design and Construction
The inner and outer hubs are designed with set screws for secure attachment, and optional containment barriers are available separately. The design ensures balanced operation and accommodates various misalignments.
Applications
These couplings are particularly suited for environments involving highly toxic or corrosive chemicals, providing a safe and efficient solution for torque transmission without physical contact.

Co-Axial Couplings Kontaktfreien Drehmomentübertragung Magnetkupplungen bieten eine berührungslose Übertragung des Drehmoments. Sie werden typischerweise für dichtungslose Anwendungen eingesetzt; sie verhindern, dass korrosive, giftige oder entflammbare Flüssigkeiten in die Atmosphäre austreten. Durch den Antrieb einer Magnetnabe wird das Drehmoment magnetisch auf die andere Magnetnabe übertragen. Dies kann durch die Luft oder durch eine nichtmagnetische Einschlussbarriere wie Edelstahl oder Glasfaser erfolgen, was eine vollständige Isolierung der inneren Magnetnabe von der äußeren Magnetnabe...
