# Machine rotary bushing inserts

They improve the durability and performance of bushings in rotating systems.

Family: Mechanical applications

## Processes
- Continuous rotation
- Dry sliding

## Challenges
- Bushing wear
- Need for relubrication
- Elevated temperature

## Advantages
- Self-lubrication
- Modular replacement
- Good dry-running behavior

## Limitations
- Oxidation in air at high temperature without protection
- Lower mechanical strength than structural metals
- Requires grade selection by load and environment
