A connecting rod is an engine component that transfers motion from the piston to the crankshaft and functions as a lever arm.

A crankshaft assembly for an internal combustion engine having a one-piece elongated shaft adapted to rotate about a longitudinal axis.

An “oil-free” air compressor does not use any lubrication in the compression chamber. Instead, these compressors use alternate materials that protect the pump, such as water or a Teflon coating, and allow the mechanism to move smoothly without the need for any oil-based or synthetic lubrication.

A piston is a movable, cylindrical component that slides inside a cylinder, converting the pressure from expanding gases or fluids into mechanical work, or vice versa, by moving up and down or back and forth. Essential components like piston rings seal the cylinder, while a piston rod connects the piston to a crankshaft, which turns the linear motion into rotational energy.
