Crankshaft inserts are used to allow the crankshaft to rotate. The rotation process occurs as a result of combustion of a fuel-air mixture in the cylinders of the internal combustion engine. Friction, which is caused by increased loads, high speeds, can cause the engine to fail. To prevent this situation and reduce friction, the components are covered with the thinnest film of lubricant. The connecting rod liner along with the shaft neck is also covered with a layer of oil. So the bearing reduces friction. Unlike the main bearings, connecting rod inserts work in more loaded conditions. The part consists of two halves of metal half-rings. The upper half is subject to short, but very significant loads. The lower half of the part takes on longer loads from the inertia force of translational motion and rotating masses.
