# Continuous Drum Rotation Generates Heat and Reduces Service Life

## Continuous Drum Rotation Generates Heat and Reduces Service Life

The concrete mixer drum rotates continuously for long periods. Friction in bearings generates heat, which reduces lubrication efficiency and accelerates wear.

## Overheating Factors

- Continuous drum rotation
- High loads from mixture weight
- Inadequate cooling
- Lubricant degradation at high temperatures

## Solutions

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