ER7 / 4140 Forged Railway Wheels 850–1050mm EN13262 for Freight Wagon and Mining Rail System

1. Product Overview

Railway wheels are critical load-bearing components used in rail transport systems to ensure stable guidance, load distribution, and long-term operational safety.
Forged steel railway wheels are designed for heavy-duty applications such as freight wagons and mining rail systems.

2. Application Scenarios

These forged railway wheels are widely used in:

• Freight wagon systems
• Mining rail transport (coal, iron ore)
• Metro and light rail systems
• Crane rail and industrial rail systems
• Locomotive and heavy haul railways

3. Key Advantages

High Strength Material (ER7 / 4140 / 42CrMo)

Provides strong fatigue resistance and ensures stable performance under heavy loads.

Optimized Flange Design (28–36 mm)

Improves rail guidance and reduces derailment risk during operation.

Controlled Hardness (260–320 HB)

Enhances wear resistance and extends service life in harsh environments.

Forging + Rolling Process

Improves internal grain structure, increasing durability and load capacity.

4. Data Support

Key parameters:

• Wheel Diameter: 850–1050 mm
• Flange Height: 28–36 mm
• Rim Thickness: 65–75 mm
• Bore Diameter: 120–260 mm
• Hardness: 260–320 HB

These parameters directly affect:

• Load capacity → diameter & rim thickness
