The connecting rod bearing, a sliding bearing , is an element whose main task is to reduce friction at the point of connection of the camshaft to the engine block. The bearing is two separable, semicircular elements that, when fitted, form a circle (or one-piece sleeves). The bearing (though not all types) also have a small groove or cut through which the lubricant is distributed. The most common reasons for rapid wear of connecting rod bearings are:

• using oil with incorrect viscosity parameters,
• incorrect installation of bearing shells,
• failure to comply with oil change intervals,
• low engine oil level,
• overloading the engine, which has not reached the correct temperature,

The first signs of wear of connecting rod bearings are an unnatural, steady knocking coming from the engine. Worn bearings must be replaced with new ones as soon as possible, replacing the faulty element too late can cause serious damage to the shaft, connecting rod or engine.
