Description

The heavy-duty twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the braking system of heavy commercial vehicles. This component is vital for maintaining reliable air supply and ensuring the operational integrity of the vehicle's air brake system through high-strength components and optimized thermal management.

K053643N55 SP1 is the OE-equivalent twin cylinder, air compressor used in the KNORR-BREMSE systems. This specific part features a Ø86.00 mm cylinder bore and a 62 mm stroke, providing a swept volume of 720cm³. It is designed to meet the rigorous technical requirements of professional workshop environments and heavy-duty fleet operations.

Designed for efficient installation, this unit includes a water-cooled configuration with specific port dimensions for inlet (M18x1,5) and outlet (M18x1,5) to manage heat during continuous operation. Workshop technicians should ensure the air unloader port (M10x1) and through-drive alignment are correctly verified during assembly to maintain optimal service intervals and system pressure stability.

This air compressor is built to withstand high-stress environments, utilizing a robust design that includes a water-cooled valve plate for enhanced thermal regulation. The integration of the ESS feature ensures that the pneumatic delivery remains stable even under fluctuating load conditions typical in long-haul transport.
