SEB22552 Piston & Ring for Knorr-Bremse Compressors

What does a compressor piston and ring do?

This compressor piston and ring set is a critical component within the air brake compressor system, ensuring efficient air compression and consistent pressure delivery. Manufactured using high-strength components, these parts are designed to withstand the extreme thermal and mechanical stresses found in heavy commercial vehicle braking systems.

Compatibility with Knorr-Bremse systems

These components are compatible with Knorr-Bremse systems. The piston diameter is specifically sized at 78.00mm (STD) to match original equipment specifications, ensuring a precise seal within the cylinder bore to prevent pressure loss.

Installation and maintenance guidance

For successful installation, technicians should verify that the ring grooves and pin diameter match the existing compressor configuration exactly. It is essential to check end gap clearances according to the service manual to ensure proper lubrication and prevent premature wear of the cylinder liner.

Troubleshooting and inspection

Regular inspection of the piston and rings during routine maintenance can help prevent system failures. Ensuring the piston surface remains free of scoring is vital for maintaining the integrity of the pneumatic braking circuit.

OE cross-reference
