# Contamination by Food Particles, Flour, Sugar, and Dust

## Contamination by Food Particles, Flour, Sugar, and Dust

In the food industry, bearings are exposed to particles of flour, sugar, spices, and other food products. These contaminants penetrate the bearing, mix with the lubricant, and form an abrasive paste that accelerates wear.

## Types of Contaminants

- Flour dust forms deposits and clogs seals
- Sugar crystals act as an abrasive
- Grease deposits attract other particles

## Protection

Bearings with labyrinth seals, protective washers, and self-closing seals are used. Regular maintenance and lubricant replacement are recommended.
