Structure Characteristics and Applications:

    FB090 wrapped bronze bushing is made of tin-bronze CuSn8 with its surface punched with diamond oil sockets which are preserved for oil saving. It has good anti-fatigue, anti-erosion anti-abrasion and load capacity. The products are widely applied in conditions of heavy load but low running velocity, such as on agricultural, construction and engineering machines.

Material Structure:

     High-density bronze is rolled into shape or oil bags and oil holes are specially integrated into the inner surface to reduce the wearing and prolong the services hours. Besides, it has excellent anti-corrosion functions.
