EN13262 ER7 Railway Wheels 500mm for Locomotive and Freight Rail Applications

1. Product Overview

Railway wheels are critical load-bearing components used in rail transport systems to ensure safe guidance, load distribution, and long-term operational stability.
Forged steel railway wheels are designed for locomotive and heavy-duty rail applications where high strength and durability are required.

2. Application Scenarios

These railway wheels are widely used in:

• Locomotive systems
• Freight wagons
• Mining rail transport
• Industrial and crane rail systems
• Metro and light rail vehicles

3. Key Advantages

High Strength Material (ER7 / 4140 / 42CrMo)

Ensures excellent fatigue resistance and structural integrity under continuous heavy loads.

Optimized Flange Design (28–36 mm)

Provides stable guidance on rails and reduces derailment risks.

Controlled Hardness (260–320 HB)

Improves wear resistance and extends service life in harsh environments.

Forging + Rolling Process

Enhances internal density and mechanical performance for long-term reliability.

4. Data Support

Key performance parameters:

• Wheel Diameter: 500 mm
• Flange Height: 28–36 mm
• Rim Thickness: 60–70 mm
• Bore Diameter: 100–220 mm
• Hardness: 260–320 HB

These parameters directly affect:

• Load capacity → diameter and rim thickness
• Wear resistance → hardness
• Running stability → flange geometry
