What is cross-head?

Cross-head is a component of reciprocating engines that helps to convert the linear motion of the pistons into rotary motion of the crankshaft. It is a mechanism that connects the piston rod to the crankshaft in a reciprocating engine and is used in a variety of industrial applications such as steam engines, diesel engines, and compressors. The cross-head minimizes wear and tear on the cylinder walls by guiding the piston rod in a straight line and also helps to reduce the friction between the piston and the cylinder walls. It is typically made of steel or other high-strength metals and is designed to withstand high stress and torque loads.
