The Problem of Electrical Erosion
Electric locomotives and EMUs use traction motors that generate stray currents. These currents flow through bearings, causing electrical erosion—microscopic damage to raceways and rollers.
Causes of Electrical Erosion
- Stray currents from traction motors
- Static electricity from friction
- Induced currents from catenary systems
- Grounding faults
Consequences of Electrical Erosion
- Pitting (spot corrosion) on raceways
- Increased noise and vibration
- Premature wear
- Risk of bearing failure
MS Bearing Solutions
- Ceramic insulating bearings (Si3N4)
- Bearings with insulating coating (aluminum oxide)
- Plastic separators with insulating properties
- Special greases with anti-corrosion additives
