What is a crosshead on an air compressor?

A crosshead on an air compressor is a component that connects the piston to the crankshaft, allowing for the conversion of rotary motion into linear motion. It typically guides the piston as it moves within the cylinder, ensuring smooth operation and minimizing wear. Crossheads are commonly used in larger, heavy-duty air compressors to handle high pressures and loads efficiently. Their design helps maintain alignment and stability during the compression process.
