FB09G bronze solid lubricating bearing

  • parameters

Since the copper alloy material having a high elongation is used as the base material, an extremely thin rolled sleeve can be produced, and the ideal filler is a lubricant. Therefore, the material is used in the automobile transmission shaft to be used as a wear-resistant bushing, and can also be used in other occasions without oil lubrication.
