26 11 50 Knorr-Bremse Compatible Compressor Cylinder Head

What does a compressor cylinder head do?

This compressor cylinder head acts as the cast service component that sits on top of an air brake compressor's cylinder block. It is designed to seal the compression chamber from above, allowing workshop technicians to rebuild a compressor in place rather than replacing the entire unit. This component is vital for governing both the air output and the running temperature of the unit.

System compatibility and fitment

This part is compatible with Knorr-Bremse systems and Bendix systems. It is specifically engineered to meet the rigorous demands of heavy commercial vehicle braking architectures, ensuring reliable performance under sustained pressure.

Installation and maintenance guidance

When performing maintenance, technicians should inspect the valve seats and internal air passages within the head to ensure optimal sealing. Proper installation is required to maintain correct compression ratios and prevent pressure leaks within the pneumatic system.

Troubleshooting and selection

If you notice a drop in air pressure or increased operating temperatures, inspecting the cylinder head may be necessary. Consult your authorized distributor to ensure correct fitment for your specific compressor architecture.
