In the realm of automotive engineering, the crankshaft thrust bearing plays a pivotal role in ensuring the smooth and efficient operation of an engine. It is a crucial component that prevents axial movement of the crankshaft, allowing it to rotate freely while withstanding the immense forces exerted upon it.
A crankshaft thrust bearing is typically composed of two half-bearings that surround the crankshaft. The inner half-bearing is attached to the crankshaft, while the outer half-bearing is housed within the engine block. This arrangement allows the crankshaft to move axially within a limited range, while preventing excessive movement that could lead to damage or failure.
