Support the Crankshaft:
Crankshaft bearings serve as the critical support between the crankshaft and the crankcase, bearing the weight of the crankshaft and forces from the pistons and connecting rods. They ensure the crankshaft maintains smooth rotation at high speeds, enabling the engine to function properly.

Reduce Friction:
The surface of crankshaft bearings is typically coated with lubricating oil, forming a lubricating film where it contacts the crankshaft. This effectively reduces friction between the crankshaft and bearings, helping to lower energy loss and heat generation, which enhances engine efficiency and longevity.

Transmit Power:
By connecting the crankshaft to the crankcase, crankshaft bearings play a crucial role in transmitting the rotational power of the crankshaft to other engine components, such as the transmission system and accessories. This ensures smooth power transfer, allowing the engine to operate efficiently.

Absorb Vibrations:
The design and materials of crankshaft bearings help absorb vibrations and shocks generated during engine operation. This reduces the impact on other engine components and contributes to the overall stability and smooth operation of the engine.
