Description
This high-strength component is designed to provide reliable performance within the pneumatic systems of heavy commercial vehicles. As a single cylinder air compressor, it plays a vital role in maintaining consistent air pressure for braking and suspension systems. The part is engineered with a robust structure to withstand demanding operating conditions in the heavy-duty sector.
The II31951 product is the OE equivalent of the KNORR-BREMSE II31951 Single Cylinder, Air Compressor used in KNORR-BREMSE systems. This part features a cylinder diameter of Ø88.00 mm and a 50mm stroke, ensuring precise volumetric output. It is engineered for water-cooled applications with specific port dimensions for reliable integration.
For workshop technicians and fleet managers, this component offers a precise fit for the air brake system. Maintenance should focus on ensuring the water inlet and outlet ports (M22x1,5) are free from debris to maintain optimal cooling efficiency. Regular inspection of the through-drive and connection points is recommended to ensure long-term system stability.
