LK8901 KNORR-BREMSE Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide reliable air pressure within the pneumatic braking system of heavy commercial vehicles. Designed with a water-cooling mechanism to ensure optimal thermal management during operation, it maintains high performance under demanding conditions. The robust construction ensures long-term stability in the air brake system.

The LK8901 is the OE equivalent of the KNORR-BREMSE single cylinder air compressor used in compatible heavy commercial vehicle systems. This component features a Ø92.00 mm cylinder bore and a 54 mm stroke to deliver a swept volume of 360cm³. It is fully compatible with KNORR-BREMSE hardware and is designed for precise integration into the vehicle's air supply architecture.

For workshop technicians, this unit provides a seamless fit with its M26x1,5 air ports and M16x1,5 water ports. The through-drive design and water-cooled valve plate functionality are critical for maintaining consistent pressure levels. Regular inspection of the water inlet and outlet connections is recommended to ensure optimal cooling efficiency.

Maintaining the integrity of the air brake system requires high-strength components like this one to prevent pressure drops. This part serves as a vital replacement for maintaining vehicle safety and operational readiness in professional fleets.
