![]() ![]() ![]() Copper based and aluminum based bearing alloys are commonly used in hard matrix and soft texture. ![]() The concave convex gap between the soft substrate and the hard point is also conducive to the storage of lubricating oil.īabbitt alloy belongs to hard point structure with soft matrix. Soft base can bear impact and vibration, good running in hard point can reduce the contact surface with the shaft, reduce the friction coefficient, reduce wear, good wear resistance. There is strong friction between sliding bearing and high-speed and heavy-duty shaft, so the microstructure of sliding bearing alloy is required to have two kinds: hard point on soft matrix and soft point on hard matrix. Antimony and copper are used to improve the strength and hardness of the alloy. The main composition of babbitt alloy is tin, lead, antimony and copper. Because of its white, also known as white alloy. They are composed primarily of tin, copper, andantimony, with traces of other metals added in some cases andlead substituted for tin in others.TIN BASED ALLOYS CHEMICAL COMPOSITION (%)CHART. In present-day usage the term is applied to awhole class of silver-white bearing metals, or “white metals.”These alloys usually consist of relatively hard crystalsembedded in a softer matrix, a structure important for machinebearings.
