E12-1 corrosion resistant brake cylinder is a key actuator of the foundation braking system for standard gauge freight trains. The cylinder body and exposed parts are treated with special anti-corrosion coating and corrosion-resistant base material, effectively resisting erosion from rain, snow, salt spray and mining dust to extend service life. Driven by compressed air, the brake cylinder pushes the piston to generate thrust, and transmits braking force through the brake lever mechanism to realize braking and releasing of freight wagons. Manufactured in strict accordance with relevant railway freight industry standards, this product adopts aging-resistant sealing parts with reliable air tightness and smooth action response. It can adapt to long-term cyclic start-stop conditions of heavy-haul freight vehicles. Easy for maintenance and on-site inspection & replacement, this brake cylinder is widely matched with various standard gauge freight wagons including open-top wagons, covered wagons and tank wagons.

E12-1 Brake Cylinder

Application Scope

Compliant with UIC international railway standards, matched to 12-inch piston air brake systems of railway freight gondolas, covered wagons, tank wagons and export railway freight cars, serving as the core executive component of foundation braking system.

Core Function

Convert compressed air pressure delivered by distribution valve into linear mechanical thrust. The push rod drives brake levers and brake beams to press brake shoes against wheel treads for train deceleration and stopping. During release, built-in reset assembly retracts the piston automatically to separate brake shoes from wheels and release braking force.

Compatibility

Suitable for cross-border export railway wagons, industrial mining private freight cars, standard/narrow gauge general cargo carriages, compatible with 600kPa air brake pipeline systems.

Integrated Spun Cylinder, High Sealing & Long Service Life
Spinning forming cylinder without welding seams; built-in low-temperature resistant rubber diaphragm piston assembly, no hardening or air leakage under -50℃ extreme cold, stable air tightness, 50% longer overhaul cycle.
