1. What It Is (Product Overview)

Railway wheels are core load-bearing components used in freight wagon systems to ensure stable guidance, load distribution, and long-term operational safety.
These forged ER7 railway wheels are specifically designed for continuous heavy cargo transport under high-load railway conditions.

2. Where It Is Used (Application Scenarios)

This type of railway wheels is widely used in:

• Freight wagon systems
• Bulk cargo rail transport
• Port and logistics rail networks
• Industrial material handling rail lines
• Long-distance freight railway systems

3. Why Choose It (Key Advantages)

ER7 Material (EN13262 Standard)

Provides high fatigue resistance and stable mechanical performance under repeated loading cycles.

Optimized Wheel Diameter (840–1050 mm)

Ensures compatibility with standard freight wagon systems and improves load distribution.

Controlled Hardness (260–320 HB)

Balances wear resistance and toughness, reducing surface cracking and extending service life.

Reinforced Rim Thickness (65–75 mm)

Improves resistance to deformation and increases durability under heavy loads.

Forging + Rolling Process

Enhances grain structure, improving internal density and long-term reliability.

4. Data Support (Performance Explanation)

Key performance parameters:

• Wheel Diameter: 840–1050 mm
• Flange Height: 28–36 mm
• Rim Thickness: 65–75 mm
• Bore Diameter: 120–260 mm
• Hardness: 260–320 HB

These parameters directly influence:

• Load capacity → determined by diameter and rim thickness
• Wear resistance → controlled by hardness level
• Running stability → ensured by flange geometry
• Service life → affected by material and heat treatment

6. Selection Guide  (MOST IMPORTANT)

By Application

• Freight wagon → ER7 (standard choice)
• Heavy freight → ER8 (higher strength)
• Logistics rail → ER7

By Load Capacity

• Medium load → ER7
• Heavy load → ER8
• Continuous heavy-duty → reinforced rim recommended

By Wheel Diameter

• 840–920 mm → standard freight wagons
• 920–1000 mm → medium-heavy freight
• 1000–1050 mm → heavy-duty freight systems

7. What Problem It Solves

These railway wheels help solve:

• Rapid wear under continuous freight transport
• Frequent maintenance in logistics systems
• Load instability in heavy cargo movement
• Short lifespan of low-grade wheels

They provide stable long-term performance, reduce maintenance frequency, and improve transport efficiency.

8. FAQ

Q1: What material is recommended for freight railway wheels?
ER7 is the standard choice, while ER8 is recommended for heavier load conditions.

Q2: How to choose the correct wheel diameter?
It depends on wagon type, axle load, and rail system specifications.
