Crankshafts and bearings are essential components of any internal combustion engine. They work together to convert the reciprocating motion of the pistons into rotational motion that drives the wheels of your vehicle. Without these two components, your engine would not be able to function.
The crankshaft is a long, forged steel shaft that runs through the center of your engine block. It has a series of throws, or cranks, that are offset from the center of the shaft. The connecting rods from the pistons are attached to these throws. As the pistons move up and down, they turn the crankshaft, which in turn drives the flywheel and the transmission.
Bearings are used to support the crankshaft and reduce friction between the crankshaft and the engine block. They are typically made of a soft metal, such as copper or lead, and are lined with a thin layer of antifriction material, such as babbitt. The bearings are located at each end of the crankshaft and in the center of the engine block.
The crankshaft and bearings work together to convert the reciprocating motion of the pistons into rotational motion. As the pistons move up and down, they turn the crankshaft. The crankshaft then turns the flywheel, which in turn drives the transmission. The bearings reduce friction between the crankshaft and the engine block, which helps to keep the engine running smoothly.

The following tables provide additional information about crankshafts and bearings:
Crankshaft | Bearings |
---|---|
Type | Journal, thrust, and connecting rod |
Material | Forged steel, cast iron, or nodular iron |
Dimensions | Determined by the engine size and type |
Function | Converts reciprocating motion into rotational motion |
Maintenance | Inspect regularly for wear and tear |
Type of Bearing | Material | Function |
---|---|---|
Journal bearing | Copper or lead lined with babbitt | Supports the crankshaft and reduces friction |
Thrust bearing | Babbitt or bronze | Prevents axial movement of the crankshaft |
Connecting rod bearing | Copper or lead lined with babbitt | Connects the connecting rod to the crankshaft |
Crankshaft and Bearing Problems | Symptoms | Causes |
---|---|---|
Crankshaft failure | Knocking or ticking noise, loss of power, increased oil consumption, engine overheating | Worn or damaged crankshaft, loose connecting rod |
