The JF800 Bimetallic Bearing Bushes, also known as SAE797-compliant bearing bushes, are specifically designed for connecting rods in automotive and industrial engines. These bearing bushes feature a unique bimetal construction, combining a steel backing with a bronze overlay, to provide superior wear resistance and durability.
The steel backing offers the necessary strength and rigidity to withstand the dynamic loads and pressures generated by the reciprocating motion of the connecting rod. The bronze overlay, on the other hand, provides excellent tribological properties, including low friction and good wear resistance, ensuring smooth and efficient operation of the engine.
One of the key features of the JF800 Bimetallic Bearing Bushes is the presence of an oil groove. This groove allows for the distribution of lubricant throughout the bearing bush, reducing friction and wear even further. The oil groove also helps to dissipate heat generated during operation, preventing thermal damage to the bearing bush.
The combination of the steel-bronze bimetal construction and the oil groove makes the JF800 Bimetallic Bearing Bushes an excellent choice for demanding engine applications. They are widely used in automotive engines, as well as in industrial engines such as diesel engines, gas engines, and compressors.
The precision manufacturing process ensures that the JF800 Bimetallic Bearing Bushes fit precisely into the connecting rod and crankshaft journals. This precise fit reduces friction and wear, improving engine efficiency and durability.
Overall, the JF800 Bimetallic Bearing Bushes with Oil Groove are reliable and robust components that offer superior wear resistance and durability in a variety of engine applications. Their bimetal construction and oil groove design ensure smooth and efficient operation of the engine, while also extending its service life.

Metallic Self-lubricating Maintenance-free Bearings
Bi-metal Bushings is a thin-walled self-lubricating composite sliding material.
It consists of a backing made of standard steel, stainless steel or bronze with a steel bronze layer applied in a combined rolling/sintering process.It is better to pay attention to the VIIPLUS Self-Lubricating Bearings solution.
VIIPLUS offers basically the same bearing characteristics as self lubricating bearings.metal but is capable of handling even higher loads and offers an economic solution to many bearing problems.
