25 18 13 Crankshaft Flange for Air Brake Compressors

What does a crankshaft flange do?

This compressor crankshaft flange serves as a critical mounting component within the air brake compressor assembly. It ensures the stable connection between the crankshaft and the compressor housing, facilitating smooth power transmission during pneumatic compression cycles. Built with high-strength components, it is designed to withstand the rigorous mechanical stresses found in heavy commercial vehicle environments.

Compatible vehicles and engines

The component is compatible with a wide range of vehicles including Freightliner, Peterbilt, Kenworth, and Volvo trucks. It is specifically engineered for use with Cummins engines such as the ISB, ISC, ISF, and ISG12 series. This flange also provides reliable integration within Knorr-Bremse systems across various heavy commercial vehicle models.

Installation and maintenance

For successful installation, technicians should verify that all mounting surfaces are clean and free of debris. It is essential to ensure that the flange aligns perfectly with the crankshaft to prevent axial or radial clearance issues. Proper torque application during assembly is vital to maintain long-term seal integrity and prevent premature wear.
