How to find the right Magnetic Bearings AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Magnetic Bearings
- Active vs passive
- Active magnetic bearings need sensors, a controller and power. Passive (permanent-magnet) bearings cannot stabilize every axis alone. A complete levitation system is engineered equipment, not a drop-in bearing.
- Backup or touchdown bearings
- Require backup bearings sized for rotor drop at speed. They protect the rotor when power fails or loads exceed capacity.
- Controller and integration
- Buy the bearing, controller and rotor design as an engineered package from the same supplier. Stability depends on tuning the control system to the specific rotor dynamics.
- Application fit
- Justified mainly for high-speed, oil-free or vacuum duty such as compressors, turbomachinery and flywheels. For ordinary machinery, rolling bearings are far cheaper and simpler.
Brands that matter
- SKF: Magnetic bearing systems from its magnetic mechatronics business, formerly S2M.
- Waukesha Bearings: Active magnetic bearing systems for turbomachinery.
- Calnetix Technologies: Magnetic bearings and high-speed machinery.
- MECOS: Swiss active magnetic bearing specialist.
What to avoid
- Levitation novelty kits listed as magnetic bearings
- Standard ball bearings sold under a magnetic label
- Buying a magnetic bearing without a matched controller and backup bearings
