The Role of Main Bearings:

Main bearings are critical components in the operation of machinery, playing a key role in supporting the crankshaft and ensuring its smooth rotation.

 

Beyond this fundamental function, main bearings serve additional purposes:

 

1. Delivering Lubricating Oil:

The main bearings feature oil grooves and holes. As the crankshaft rotates, these features draw in engine oil and distribute it to the connecting rod bearings, providing necessary lubrication.

 

2. Protecting Bearings:

An oil film is formed between the main bearing and the crankshaft, which acts as a protective layer, reducing direct metal-to-metal contact and thus minimizing wear.

 

3. Reducing Wear:

The surface of the main bearing is precision-machined to achieve a surface roughness of less than 0.4μm, significantly reducing friction and wear during operation.

 

By fulfilling these roles, main bearings contribute to the efficient and reliable operation of the engine.
