What is a mechanical case?

The mechanical case is a sleeve -shaped lining used to reduce friction and wear between the mechanical parts or to limit or reduce the movement of parts. Sometimes they are called ordinary bearings, mechanical cases are used to align the hole in the stationary part of the mechanism and are effective in spreading friction and wear over the surface of the housing, unlike its directing to one place. The rod is therefore able to rotate inside the mechanical case with a capsule releasing the friction rod and wear of rotations. The piston rods are connected to the rotating crankshaft with the rotation of the crankshaft the pushing piston rod up and down. The steel point Piston Rod and a polished steel shaft is an opening in a stick that is lined with a case. This particular mechanical case will help from the lubrication effect of the engine oil in the scattering of the rotating shaft.

An example of an unleashed mechanical case would be thatis used during the surface of the propeller shaft on the boat with an internal engine. The propeller shaft leads from the transmission, through the hole in the fuselage and into the water. This hole or assembly is lined with an anticorrosive, polymer or bronze bearing that distracts friction and reduces the wear of the torso and shaft. In addition, this assembly is designed to prevent water from entering the ship.

Babbitt Metal, often called white metal, and plastics are used much more often than any other materials in the production of mechanical cases due to their effects in reducing friction, as well as their low weight and relatively low costs. Other materials used in a common mechanical case include aluminum, rubber, bronze, carbon and various ceramics.

The mechanical case or an ordinary bearing should not be confused with a conventional bearing. Regular bearing is usually constructed from a more durable material, is less inclined to lubrication, unlike the introduction of lubrication and is very often in itself a moving part,as in the case of a ball bearing.
