LK4951 SP1 KNORR-BREMSE Twin Cylinder, Air Compressor

The technical performance of the air brake system relies heavily on the precision of the compressor. This twin cylinder air compressor is engineered to provide consistent air pressure through its robust design and high-strength components. Designed specifically for heavy commercial vehicle applications, it ensures reliable operation within the pneumatic system by maintaining optimal pressure levels under demanding duty cycles.

LK4951 SP1 is the OE-equivalent Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This component features a cylinder bore of Ø86.00 and a stroke of 62 mm, providing a swept volume of 720cm³. It is designed to be compatible with KNORR-BREMSE hardware, ensuring seamless integration into the existing pneumatic architecture of heavy-duty vehicles.

For the workshop technician, this unit offers a streamlined assembly process thanks to its standardized port dimensions and water-cooling compatibility. The air inlet port (M26x1,5) and water ports (M18x1,5) are precision-engineered for secure connections. Regular maintenance and checking the water cooling lines is recommended to ensure the longevity of the component during intensive service intervals in the heavy commercial vehicle sector.
