General Information

 Part Number: It is specifically identified by the part number 4319786X, which helps in precise identification and replacement of the bearing in automotive repair and maintenance.

Function: This bearing is installed between the connecting rod and the crankshaft in an engine. Its main function is to reduce friction and wear between the moving parts, enabling the connecting rod to rotate smoothly around the crankshaft and facilitating the conversion of the piston's linear motion into the crankshaft's rotational motion.

Design and Structure
Material: Usually made of high - quality metal alloys, such as copper - lead alloys or aluminum - based alloys. These materials have excellent wear - resistance, fatigue resistance, and good thermal conductivity, which can withstand the high - temperature and high - pressure working environment in the engine.

Structure: It is typically a split - type structure, consisting of two semi - circular shells. The inner surface of the bearing is smooth and precisely machined to fit the connecting rod and crankshaft journals closely. The outer surface may have some grooves or oil holes to ensure proper lubrication and oil distribution.

Performance Characteristics
High Load - Bearing Capacity: It can bear the large dynamic and static loads generated during the engine's operation, ensuring the stable operation of the connecting rod and crankshaft under various working conditions.

Low Friction Coefficient: The smooth surface and suitable material of the bearing reduce the friction coefficient, which helps to improve the engine's efficiency and reduce energy losses.

Good Wear Resistance: Withstand the repeated friction and impact of the connecting rod and crankshaft during long - term use, having a long service life and reliable performance.

Installation and Maintenance
 Installation: During installation, it is necessary to ensure that the bearing is correctly installed in the connecting rod and crankshaft, and the clearance between the bearing and the journal is within the specified range. Improper installation may lead to abnormal wear of the bearing or even engine failure.

Maintenance: Regularly check the wear condition of the bearing. During engine oil changes, also check the oil quality and oil level to ensure sufficient lubrication of the bearing.
