Brake Block Holder Alloy Steel Casting

The brake block holder is the core fixing and supporting component of a railway vehicle's braking system, usually installed on the brake caliper or brake beam to secure the brake block in place. It is mainly made of high-strength carbon steel or alloy cast steel with heat-treated surfaces, featuring high rigidity, reliable clamping force and good fatigue resistance. It withstands intense clamping pressure, friction and vibration shocks during train braking and operation, and its performance directly affects brake block stability, braking efficiency and the running safety of railway vehicles.
