LK4952 KNORR-BREMSE Twin Cylinder, Air Compressor

This twin cylinder air compressor is engineered to provide reliable air pressure for heavy-duty pneumatic systems within the braking architecture. Designed with a focus on durability, the component features a Ø86.00 mm cylinder bore and a 54 mm stroke to deliver a consistent 630cm³ swept volume. The integration of water-cooling technology ensures stable thermal management during high-load operations, making it an essential part for maintaining optimal system pressure.

LK4952 is the OE-equivalent of the KNORR-BREMSE LK4952 twin cylinder air compressor used in heavy commercial vehicle systems. This unit is specifically engineered to meet the technical requirements of KNORR-BREMSE hardware. By utilizing high-strength components and precision-engineered ports—including M26x1,5 for air and M18x1,5 for water—it maintains seamless integration with existing pneumatic circuits.

For workshop technicians and fleet managers, installation requires careful attention to the water-cooling connections and the M18x1,5 inlet/outlet ports. The assembly is designed for heavy-duty environments where consistent air delivery is critical for safety and performance. Regular maintenance checks of the water-cooled valve plate and port integrity are recommended to ensure long-term operational stability in professional service environments.
