# Air Compressor Units: Bearings for Pneumatic Systems

## Railway Pneumatic Systems

Air compressors are a key component of railway pneumatic systems. They supply compressed air to brakes, doors, suspensions, and other equipment. Bearings in compressors operate under high pressures and speeds.

### Bearing Applications:

- Rotary compressor shafts
- Drive gears
- Electric motor bearings
- Cooling fans

### Requirements:

- High rotational speed (up to 6000 rpm)
- Resistance to high pressures
- Long service life under continuous operation
- Low noise level
