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.
This type of railway wheels is widely used in:
Provides high fatigue resistance and stable mechanical performance under repeated loading cycles.
Ensures compatibility with standard freight wagon systems and improves load distribution.
Balances wear resistance and toughness, reducing surface cracking and extending service life.
Improves resistance to deformation and increases durability under heavy loads.
Enhances grain structure, improving internal density and long-term reliability.
Key performance parameters:
These parameters directly influence:
| Item | Specification |

| Diameter | 840–1050 mm |
| Hardness | 260–320 HB |
| Standard | EN13262 |
| Flange Height | 28–36 mm |
| Rim Thickness | 65–75 mm |
| Bore Diameter | 120–260 mm |
These railway wheels help solve:
They provide stable long-term performance, reduce maintenance frequency, and improve transport efficiency.
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.
Q3: Can railway wheels be customized?
Yes, customization is available based on drawings, standards, and project requirements.
