Babbitt bearings are a type of bearing composed of a white metal alloy such as tin, copper, and antimony. They are designed to provide a bearing surface between two parts in contact with each other to reduce friction and wear. Moreover, the operation of a Babbitt bearing is surprisingly straightforward.

One of the benefits of using a soft bearing material such as babbitt, also known as whitemetal, is its capability to embed material in the bearing surface. At the end of a particle track, the particle will embed itself in the babbitt, resulting in haloes or raised regions around the embedded particle, as shown in Figure 3.

Basically, they support the weight of the shaft and provide a non-damaging surface to the high-speed shaft that rotates. The lining of a bearing is bonded with Babbitt, which is a soft alloy featuring a low-melting point. When contamination occurs or failure happens in the lubrication system, the softer alloy wears out instead of the shaft.

Babbitt metal, also called white metal, is a soft, white non-ferrous alloy used to provide a bearing surface. It has properties that help reduce friction which make it a good material to use in a plain bearing. Babbitt was first created by Isaac Babbitt. Born July 26, 1799 in Taunton, Massachusetts, Babbitt was well known as an inventor by trade.
a lead-based babbitt bearing, lead, antimony, and tin are the key elements. The melting point temperatures range from 358°F (181°C) to 479°F (249°C). Babbitt alloy metals are subject to creep at elevated temperatures within a hydrodynamic film. This occurs at around 375°F (190°C) for bearing loads below 200 psi (13.79 bar) to about

The use of bearing materials to reduce bearing friction can be traced at least back to the Roman chariot days. Soft metals such as Tin and Lead were unsuccessfully tried in the 1700's; but, it was not until 1839 that Isaac Babbitt patented a bearing with a Steel or Bronze shell lined with a Tin-base alloy.
For a long time, most camshaft bearings were made with babbitt. This material consists of mostly tin and lead. Similar to solder, it is a soft and slippery material. Babbitt was used widely due to its ability to withstand harsh conditions and hold up under foreign particle contamination, misalignment, and marginal lubrication on start up.
