BS3332/F White Metal Bearing Alloy
Lead-Rich Bearing Alloy
BS3332/F white metal bearing alloy is a lead-rich white metal bearing alloy designed for heavy-duty bearing applications where good fatigue strength, embeddability, and conformability are essential. With lead as the primary constituent and controlled levels of tin, antimony, and copper, BS3332/F provides reliable service in environments subject to shock loads and intermittent lubrication. It meets the requirements of the BS 3332:1987 standard and is widely used in industrial and automotive bearing manufacturing.
