Bearing alloy (commonly known as babbitt or white alloy)
The bearing alloy is an alloy of tin, lead, antimony or copper. It is made of tin or lead as a matrix, and contains hard grains of antimony tin (Sb-Sn) and copper tin (Cu-Sn). Hard grains act as anti-wear and soft substrates increase the plasticity of the material. The bearing alloy has a low modulus of elasticity and a low elastic limit. Among all the bearing materials, it has the best embedding and friction compliance, and it is easy to wear with the journal and is not easy to bite with the journal. However, the strength of the bearing alloy is very low. It is not possible to make the bearing bush alone. It can only be attached to the bronze, steel or cast iron bearing bush for bearing lining. Bearing alloys are suitable for heavy-duty, medium-high-speed applications and are more expensive.
