All About Engine Bearings
Engine bearing is a special product which can meet specific requirements. According to its name, we can predict that it can be used in engines. Actually, it can be applied between two parts of an engine.
It has two main functions. One is reducing friction between the rotating parts of an engine by having two lubricated different metals slide against each other. The other is supporting the crankshaft. This type of bearing also has various kinds. In order to keep the engines running smoothly, three main types of engine bearings should be applied.
The first one is the crankshaft main bearing on which the crankshafts rotate. It can be found in between the engine block and the crankshaft. And the oil film coating around the bearings is important to keep consistent to ensure the crankshafts continue to spin. Main bearings can be used in different kinds of engines, and the number used is also different. For instance, modern V8 engines have five main bearings while six cylinder engines have seven main bearings.
The second one that I have to talk about is the camshaft bearing that can be used to reduce friction with the rotation of the camshafts. What are the camshafts? They are long rods with various lobes sticking out that can either cover or uncover a valve in the engine. Besides, they are connected to the crankshafts directly or by a gear mechanism.
The last but not the least one is the connecting rod bearing which is the metal insert that protects the wear and tear in between the connecting rods and the crankshaft. The rods are the link between the pistons and the crankshaft. When the crankshaft rotates, it is the connecting rods that move the pistons down and up in their cylinder bores.
The above mentioned three main types of engine bearings have their own characteristics and significance. Due to their cooperation, the engines are kept under the smooth function.
