About the product

The main functions of connecting rod bearings include the following aspects:

Reduce friction and wear: Connecting rod bearings can effectively reduce friction between connecting rods and crankshafts, reduce energy loss, and improve engine efficiency. In addition, it can reduce the wear of the crankshaft pin and extend the service life of the engine.

Support and positioning: The connecting rod bearings ensure that the connecting rod can move accurately on the crankshaft, maintaining the normal operation order of the engine.

Dust prevention and sealing: Connecting rod bearings not only have dust prevention and sealing functions, but can also be matched with sealing components to achieve better sealing effects.

Transmission and buffering: Connecting rod bearings can transmit axial and radial forces, and play a role in buffering and absorbing vibrations during operation, making the rotation of the main axle box smoother.

Assist in heat dissipation: The engine generates a large amount of heat during operation, and the connecting rod bearings can conduct and dissipate some of the heat, ensuring that the engine operates at a suitable temperature.

The structural characteristics and working principle of connecting rod bearings:

Connecting rod bearings are usually composed of a steel base and a wear-resistant alloy layer. Common wear-resistant alloys include white alloys, copper lead alloys, and aluminum based alloys. The inner surface of connecting rod bearings is usually cast with these wear-resistant alloys to ensure good lubrication effect. In addition, the design of connecting rod bearings typically includes oil holes and oil grooves for better lubrication.

Installation and maintenance of connecting rod bearings:

When installing connecting rod bearings, it is necessary to ensure that the oil holes on the inner surfaces of the upper and lower halves are aligned with the oil holes on the connecting rod to ensure good lubrication effect. In addition, the installation of connecting rod bearings requires precise positioning measures to prevent them from moving or rotating during operation. During use, regularly check and maintain the condition of the connecting rod bearings to ensure their normal operation and extend their service life.
