LK8921 KNORR-BREMSE Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide consistent air pressure for heavy commercial vehicle pneumatic systems. Designed with a robust structure, the component ensures reliable operation under demanding workshop conditions. The integration of high-strength components and a specialized water-cooling system helps maintain optimal temperature regulation during high-load cycles.

LK8921 is the OE equivalent of the KNORR-BREMSE LK8921 Single Cylinder, Air Compressor used in KNORR-BREMSE systems. This part meets strict technical requirements for heavy-duty applications, ensuring seamless integration with existing air brake compressor architectures. The precise engineering of the cylinder bore and stroke optimizes the swept volume for maximum efficiency.

For workshop technicians, this unit offers straightforward installation thanks to its standardized port sizes and through-drive design. The water-cooled valve plate and specific M16x1,5 inlet/outlet ports are designed to handle thermal stress effectively. Regular maintenance and checking the water cooling lines is recommended to ensure the longevity of the component within the air brake system.

Detailed technical specifications include a 54mm stroke and a 360cm³ swept volume to meet original equipment performance standards. The unit is specifically designed for heavy commercial vehicle systems requiring reliable air generation through a single-cylinder mechanism.
