Railway Side Frame Alloy Steel Casting

The railway side frame is the core load-bearing structural component of a railway bogie, usually installed in pairs to connect the axle box, wheelset and bolster inside the bogie frame. It is mainly made of cast steel or welded low-alloy steel plates with machined and riveted wear-resistant linings, and has the characteristics of high strength, excellent fatigue resistance and reliable load transmission capacity. It can withstand vertical loads, lateral impacts and cyclic vibration stresses in complex railway operation conditions, and its performance directly affects the structural stability, load-bearing capacity and running safety of the railway bogie.
