Maintenance-free magnetic bearings for the industrial sector

High-speed applications require high-quality bearing solutions.
Conventional bearing systems are subject to high wear and tear in the upper speed range, or their suitability for cycle-based operation is limited. Magnetic bearings with their contactless technology are non-wearing and maintenance-free. Also, they do not require any lubrication. Active magnetic bearings perfectly complement KEBA’s automated drive solutions and are used in many high-speed applications.
