B16 brand babbit

Material

Babbitt is an alloy based on lead (base) and tin

View by manufacturing method

To produce it, you only need to extract its elements (or process recycled materials), because it itself is a completely man-made alloy. The finished form of babbitt is ingots, pigs weighing no more than 22 kg. To cast them, the material is carefully prepared - cleaned and degreased. When melting, the sprudin - refractory foam - is removed from the surface of the mass. Babbitt production ends with the casting of ingots. Each of them is imprinted with the company’s trademark, brand and serial number of the heat.

Chemical composition

Sn content: 15.0 - 17.0% Pb content: 64.0 - 68.5%

Type by purpose

Each type of part requires its own brand of babbitt alloy: Connecting rod bearings (joint of the piston and crankshaft) - BM brand. Used for tractors. They require replacement with new ones every thousand kilometers. Main bearings use B88 babbitt, created specifically for high speeds and high dynamic loads. Therefore, this brand is successfully used for medium-speed and high-speed diesel engines. Bearings for ship water pipelines and compressors - the BN variety, ideal for medium loads and speeds. Heavy engineering - the properties of grade B16 babbitt are perfect
