# Thermal Expansion and Temperature Fluctuations Affect Bearing Clearances

## Thermal Expansion and Temperature Fluctuations Affect Bearing Clearances

During rolling mill operation, bearings are subject to significant temperature fluctuations. Thermal expansion of rolls and housings alters bearing clearances.

## Temperature Impact

- Thermal expansion of rolls
- Change in bearing clearances
- Condensation during cooling
- Lubricant degradation at high temperatures

## Solutions

Bearings with increased clearances are used to compensate for thermal expansion. Bearings with heat-resistant lubricants are employed. A cooling system is recommended.
