Customized Material Railway Spare Parts , Rail Wagon Bogie Adapter

Adapter is one of the important parts of railway locomotive and vehicles. The adapter’s function is to connect the wheel set and side frame on the bogie, to transform the rolling of the wheels on the track through the side frame into the movement of the car body, and to transfer the load of the car body to the bearing and axles, which plays an important role in preventing eccentric load of the axles.

Most of the adapters for three-piece truck bogies are made of cast steel Class C material, designed according to AAR M 201. The manufacturing process complies with AAR M-924. Due to optimization design, Tieke could provide suitable adapters compatible with different bearing sizes as below table.
