# Lubricant Degradation and Shortage Under High Loads and Temperatures

## Lubricant Degradation and Shortage Under High Loads and Temperatures

In rolling mills, bearings operate under extreme loads and temperatures. High temperatures cause lubricant degradation, while significant loads squeeze it out of the contact zone.

## Causes of Degradation

- High temperatures from metal deformation
- Significant pressures in the contact zone
- Lubricant squeeze-out under impact loads
- Lubricant oxidation at high temperatures

## Solutions

Bearings with heat-resistant lubricants are used. Bearings with increased internal clearances are employed. The use of a forced circulation lubrication system is recommended.
