Steel railway wheels for metro and passenger rail systems are designed to provide stable running performance, smooth wheel-rail contact, and long-term operational reliability.
These forged wheels are suitable for urban transit systems operating under frequent acceleration and braking cycles.
Manufactured according to EN13262 requirements, they provide balanced wear resistance and fatigue performance for passenger applications.
These steel railway wheels are widely used in:
ER7 provides balanced strength and wear resistance.
ER8 can be selected where higher loads and extended service life are required.
The wheel profile is optimized to improve wheel-rail contact conditions and support smooth operation.
Suitable for metro cars, passenger rail vehicles, and urban transit fleets.
This hardness range supports both wear resistance and running comfort.
Forging and CNC machining improve profile accuracy and operational consistency.
Key parameters:
These parameters affect:
Passenger Comfort → wheel profile accuracy and stability
Operational Safety → flange geometry and dimensional precision
Service Life → hardness and material performance
Maintenance Interval → wear resistance and heat treatment quality
System Compatibility → bore dimensions and wheel diameter
