SEB22551 Piston and Ring for Knorr-Bremse Compressors

What does a compressor piston and ring do?

This compressor piston and ring set is engineered to restore essential compression functionality within air brake systems. These high-strength components are designed to withstand the high-pressure environments found in heavy commercial vehicle compressors, ensuring consistent air delivery for the braking system.

Compatibility with heavy commercial vehicles

The unit is compatible with Knorr-Bremse systems and is designed to match specific cylinder bore requirements. It serves as a reliable replacement for worn components, maintaining the integrity of the pneumatic circuit in heavy-duty applications.

Installation and maintenance guidance

Installation requires precise verification of the piston diameter and ring groove arrangement. When performing maintenance, technicians should ensure that the piston diameter matches the cylinder bore exactly and check that the ring end gap complies with the manufacturer's specifications to prevent pressure loss.

System performance and selection

Maintaining proper clearance between the piston and cylinder wall is critical for preventing premature wear. Using high-strength components helps maintain system pressure stability during heavy-duty operation. Consult your authorized distributor.
