N13262 Steel Railway Wheels 700–920mm for Metro and Passenger Rail Systems

1. What It Is

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.

2. Where It Is Used

These steel railway wheels are widely used in:

• Metro train systems
• Urban rail transit networks
• Passenger rail vehicles
• Light rail transit systems
• Suburban rail transportation
• Electric multiple unit (EMU) systems

3. Why Choose It

ER7 / ER8 Material Selection

ER7 provides balanced strength and wear resistance.

ER8 can be selected where higher loads and extended service life are required.

Passenger-Oriented Wheel Design

The wheel profile is optimized to improve wheel-rail contact conditions and support smooth operation.

Moderate Diameter Range (700–920 mm)

Suitable for metro cars, passenger rail vehicles, and urban transit fleets.

Stable Hardness Range (250–320 HB)

This hardness range supports both wear resistance and running comfort.

Precision Forging and Machining

Forging and CNC machining improve profile accuracy and operational consistency.

4. Data Support

Key parameters:

• Wheel Diameter: 700–920 mm
• Flange Height: 28–35 mm
• Flange Thickness: 27–33 mm
• Rim Thickness: 60–75 mm
• Bore Diameter: 110–240 mm
• Hardness: 250–320 HB

These parameters affect:

Passenger Comfort → wheel profile accuracy and stability
