# Impact of Rainwater, Dust, Sludge, and Metal Contaminants

## External Impact Factors

Railway bearings operate under constant exposure to external factors:

- Rainwater and snow
- Dust and dirt from track beds
- Sludge and sand from shoulders
- Metal particles from rails and wheels
- Anti-icing reagents

## Consequences of Contamination

- Corrosion of raceways and rollers
- Abrasive wear from particles
- Seal damage
- Lubricant degradation

## Protection Solutions

- Multi-layer labyrinth seals
- Corrosion-resistant coatings (zinc, nickel)
- Stainless steel for critical applications
- Special lubricants with water-repellent properties
