Bearing alloy introduction
Bearing alloys (babbitt) are widely used. They are usually available in two types: tin-based bearing alloys and lead-based bearing alloys, which have the characteristics of running fast and can easily make the surface very smooth. They are usually attached to the bearing base of the steel as a bearing liner. Babbitt bearings have good adaptability and are self-adjusting for smaller misaligned or defective shafts. Since the proper amount of dust or foreign matter entering the lubricant can be absorbed by the soft material to prevent the gluing failure of the shaft, the embedding property makes them excellent bearing materials. The journal material can be mild steel, hard steel or cast iron.
