What is a Mechanical Bushing?
A mechanical bushing is a sleeve-shaped lining utilized to reduce friction and wear between mechanical parts or to restrain or constrain the motion of the parts. Sometimes called plain bearings, mechanical bushings are used to line a hole in a stationary part of a mechanism and are effective in spreading friction and wear over the surface of the bushing as opposed to directing it to one spot. The most basic elements of bushing mechanics consist of a rotating rod or shaft running through a hole that is lined with a mechanical bushing. The rod is thus able to rotate inside the mechanical bushing with the bushing relieving the rod of the friction and wear generated by the rotation. In an internal combustion engine, the crankshaft is an example of the typical lubricated rolling mechanical bushing/plain bearing. The piston rods are connected to the rotating crankshaft with the rotation of the crankshaft pushing the piston rods up and down. The connecting point of the steel piston rod and th
