OM 366 Piston Ring 75.0mm for Daimler-Benz Air Compressor - ISO 9001 Certified OEM Parts

Proper installation requires maintaining appropriate fit gap between piston ring and piston to ensure optimal sealing performance while preventing operational faults from excessive tightness or looseness. Handle with care during installation to avoid collision damage.

The manufacturing process includes material preparation, casting, precision machining, and heat treatment. Raw materials undergo inspection and preparation before being melted and injected into molds to form initial circular structures.

Piston rings typically consist of multiple rings with close side connections, including oil rings, oil control rings, and upper/lower spiral grooves. Each structural variation serves specific functions such as cylinder sealing, heat conduction, and lubrication.
