Product Application
The connecting rod bearing (also called the “small bearing”) is a vital sliding bearing component installed at the connection between the connecting rod big end and the crankshaft connecting rod journal. It consists of an upper half and a lower half. Its main functions include:
- Wear reduction – The bearing alloy layer contacts the crankshaft journal directly, with an oil film separating the surfaces to reduce friction and protect the crankshaft.
- Connection and support – It precisely connects the connecting rod big end to the crankshaft journal and withstands cyclic impact loads from combustion pressure and inertia.
- Power transmission – It transfers force from the piston to the crankshaft, converting reciprocating motion into rotational motion.
- Lubrication and cooling – Oil grooves and holes supply lubricating oil to form an even oil film, reducing friction and carrying away heat.
If a con rod bearing becomes damaged (such as burning or seizure), it can lead to reduced engine power, abnormal noise, or even engine failure. Regular oil changes, clean lubrication systems, and avoiding prolonged overload operation are key to preventing bearing failure.
