# Heavy Contamination from Dust, Sand, Dirt and Debris

## Problem of Contamination

Construction equipment operates in conditions of heavy contamination: dust, sand, dirt, debris. These contaminants penetrate into bearings and cause abrasive wear.

## Sources of Contamination

- Dust and sand — from work on construction sites

- Dirt — from work in wet weather

- Debris — from construction materials

- Metal shavings — from cutting and welding

## Consequences

- Abrasive wear of raceways

- Damage to the separator

- Loss of lubricant

- Premature failure

## MS Bearing Solutions

## We offer bearings for contaminated conditions:

- Bearings with labyrinth seals

- Ceramic coatings for protection against abrasive wear

- Special lubricants with extended service life

- Pillow block bearings with protective covers

## Order bearings for operation in contaminated conditions.
