# Pantograph Systems: Bearings for Current Collection Devices

## Electric Locomotive Pantographs

A pantograph is a device used to draw electric current from the overhead contact line. It includes numerous articulated joints with bearings that enable mobility and pressure against the contact wire.

### Applications of Bearings:

- Lower and upper lever joints
- Pantograph head pivot shafts
- Springs and dampers
- Lifting/lowering mechanisms

### Requirements:

- High electrical conductivity (for current dissipation)
- Resistance to electrical erosion
- Operation at high speeds (up to 350 km/h)
- Vibration resistance
