Air brake systemsare traditional product for freight wagons. We can provide reasonable air brake systems based on different standards required. The system cover TB/T，AAR，ROA，UIC standards，also provide customization services.
Brake System Composition
East Railway can also supply the below brake system components：



 

Main lever of the brake beam be made of standard “X”section steel，and the brake holder is casting part. The brake holder is connects with forging link rods. Thebrake beam is basic brake rigging of the bogie，and the air brake system through this device transfer the brake force to stop the wagon.

The wheel set is key component of the Railway Bogie. It is also the most common and important spare part in railway industry.
One-wheel set contains two wheels，one axle，and two bearings. Depend on different application methods other special parts including gears，brake discs，axle box etc.


They could be used on wagon，locomotive，passenger car and more. The wheel has a cast wheel or a forged wheel, the axle and bearingscan be chose to the customer requirements.Vehicle and bogie performance parameters will define what wheel set configuration is required.

Side bearing and wearing parts between the bogie and vehicle， protect and extend the life cycle the vehicle and bogie.
It is divided into elastic and inelastic type，according to the performance and parameter requirements.

Wearing parts are typically used in fragile joints to protect adjacent parts. Usually the wear parts are made of wear resistant metal or composite materials.
