FB69-4 Oil Impregnated Bronze Flanged BearingBost Bronz is Boston Gears all purpose, oil impregnated, porous bronze bearing material. It is manufactured using the powdered metal process with the purest metal powders. This process ensures the uniform distribution of pores between the bronze particles which absorb the oil by capillary action. In addition, Bost Bronz has a self contained oil supply (approximately 20% by volume) which provides a uniform protective film over the entire bearing
