# Corrosion from Seawater and Moisture Damages Bearing Surfaces and Lubrication

## Seawater Corrosion

Seawater is one of the most aggressive environments for bearings. Its salt content, humidity, and chemical impurities cause severe corrosion.

## Corrosion Factors

- High salt content — 3.5%
- Constant humidity
- Splashes and spray
- Condensation from temperature fluctuations

## Consequences

- Corrosion of raceways
- Seal damage
- Lubricant contamination
- Accelerated wear

## MS Bearing Solutions

We offer corrosion-resistant stainless steel bearings with protective coatings.
