Wheels and axles are the most important parts of the train. They can ensure the smooth operation and safety of railway rolling stock from under the floor.
With the improvement of the acceleration and braking performance of trains, the conditions for the use of wheels become more and more severe. The quality of the wheels we produce is absolutely reliable.

Types of train wheels:
1. Wagon wheels
Used for railway freight car bogies, running speed up to 120km/h, wheel load. Truck wheels usually use tread brakes.
There are usually two types of manufacturing, casting and rolling. Use basin wheel webs when casting. For rolling, the web is usually S-shaped.
The wheels are manufactured in accordance with TB/T 2817, AAR M-107/208, BS 5892-3 and EN 13262 standards.
2. Passenger car wheels
For railway passenger car bogies, the wheel running speed is about 120km/h or more, and the wheel load is light.
They usually use shaft disc brakes or wheel disc brakes.
Passenger car wheels are manufactured by rolling. According to different braking methods, the webs can be S-shaped, double S-shaped or straight.
In the manufacturing process, it complies with manufacturing standards TB/T 2817/2708, AAR M-107, BS 5892-3 and EN 13262.
3. Locomotive wheels
There are two types of locomotive wheels: integral wheels and split wheels.
The diameter of locomotive wheels is larger than that of ordinary wheels, usually over 1000mm.
Comply with manufacturing standards TB/T 2817, AAR M-107/208, BS 5892-3, IRS R-34 and EN 13262.
