LK 4951 SP1 KNORR-BREMSE Twin Cylinder Air Compressor

This heavy-duty grade air compressor is engineered to provide consistent pneumatic pressure within the braking system. Designed as a high-strength component, it features a twin cylinder configuration with a 720cm³ swept volume and a 62 mm stroke to ensure optimal performance under demanding operational cycles.

LK 4951 SP1 is the OE-equivalent of the KNORR-BREMSE LK 4951 SP1 twin cylinder air compressor used in KNORR-BREMSE systems. This part is also compatible with the technical specifications of 7600 880 004, 1732078, and 1775248. The assembly is designed for precision fitment within heavy commercial vehicle pneumatic circuits.

For workshop technicians, this unit features a water-cooled design with M18x1,5 inlet/outlet ports and an M26x1,5 air inlet/outlet configuration. The integration of the ESS feature and a water-cooled valve plate ensures stability during high-load service intervals. Maintenance should focus on checking the M10x1 air unloader port and ensuring proper water cooling flow to maintain system integrity.

This component is essential for maintaining the air pressure required for reliable braking performance. The robust construction and precise port dimensions allow for seamless installation in professional workshop environments.
