25 29 12 Crankshaft Flange for Air Brake Compressors

What does a crankshaft flange do?

This crankshaft flange serves as a critical component within the air brake compressor assembly, ensuring the structural integrity of the reciprocating mechanism. Manufactured from high-strength components, it maintains precise alignment during high-pressure pneumatic cycles, which is essential for reliable braking performance in heavy commercial vehicles.

Compatible vehicles and engines

This component is specifically designed to be used with Cummins ISF engines and is compatible with Knorr-Bremse systems. It is fitted to various heavy-duty models including Foton MPX-S, JAC Sunray, Dongfeng EQ5041, Gaz GAZelle Next, and Iveco Daily. Other compatible applications include Foton Aumark, Gaz Valday, Foton Tunland, Dongfeng Captain, Foton Ollin, JAC HFC1091, Foton View, and Gaz GAZon Next.

Installation and maintenance

For optimal performance, technicians should inspect the flange during routine compressor maintenance. Ensuring the mounting surface is free of debris and that the fastening torque meets technical requirements will prevent air leaks and vibration issues within the pneumatic system.

System reliability

When replacing worn components in the compressor crankshaft assembly, selecting a high-quality flange helps maintain consistent air pressure delivery across the entire braking system.
