5257939 Twin Cylinder Compressor for Cummins

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the air brake system of heavy commercial vehicles, utilizing two piston-cylinder assemblies to generate compressed air. By producing two compression strokes per crankshaft revolution, this unit delivers significantly higher air output than single-cylinder alternatives, ensuring faster reservoir filling for high-demand applications.

Vehicle compatibility and performance

This component is compatible with Cummins systems and is specifically engineered to meet rigorous industrial standards. It is suitable for heavy commercial vehicles requiring consistent air pressure for braking and pneumatic operations. The design ensures seamless integration into existing heavy-duty air brake architectures.

Technical specifications and installation

Technical specifications include a Ø86.00 cylinder bore and a 40 mm stroke, providing a swept volume of 460cm³. This water-cooled unit features M26x1,5 air inlet and outlet ports, alongside M16x1,5 water inlet and outlet ports. The through-drive design and water-cooled valve plate ensure thermal stability during continuous operation.

Maintenance and troubleshooting

To ensure proper function, technicians should verify the mounting interface and port alignment during installation. Regular inspections of the water cooling lines and air ports are recommended to maintain optimal pressure levels within the pneumatic system.
