# Engine Cooling Fans: Bearings for Ventilation Systems

## Traction Motor Cooling Systems

Traction motors of electric locomotives and EMUs generate a large amount of heat during operation. Cooling systems with fans dissipate this heat and maintain the motor’s operating temperature.

### Bearing Applications:

- Cooling Fan Axles
- Drive Shafts
- Fan Motor Bearings

### Requirements:

- High rotational speed (up to 3000 rpm)
- Low noise level
- Long service life under continuous operation
- Vibration resistance
