Product Overview
The Railway Brake Steel Back Plate is a key structural component used in freight wagons, passenger trains, metro vehicles, urban rail transit systems, and locomotives.
It serves as the load-bearing substrate for brake friction materials, connecting brake pads with the braking mechanism. During operation, it transmits braking torque and withstands continuous friction, impact loads, and high-temperature conditions, making it a critical safety part for railway operation.
With reinforced rib structures, large mounting holes, and high-strength load-bearing design, it effectively improves rigidity and anti-deformation performance of the brake assembly, ensuring long-term stable operation.
With over 40 years of casting manufacturing experience, Sangroove (Jiangsu) Machinery Co., Ltd. specializes in railway brake steel back plates, brake brackets, disc brake connectors, rail transit castings, and industrial braking components for global OEM customers.
