Types of Main Bearings Used in Marine Industry

Image
  Lead Bronze, Bi-Metal, and Tri-Metal bearings: These three types of bearings play a huge role in the marine industry. They are utilised to support rotating shafts and reduce friction to ensure smooth rotations. These bearings come with distinct benefits such as high load-bearing capacity, wear and corrosion resistance. Let us explore what these three bearings are made of, how many layers they have, and what they are used for. Lead Bronze Bearing Flash layer: This topmost layer is composed of tin and lead. It is 0.035mm thick. This layer’s job is to protect the bearing from getting corroded and dust when not being used. It flashes off when a bearing is running. Nickle Barrier: This 0.02mm thick layer - made of nickel - helps prevent corrosion and avoid diffusion of tin into bearing metal. Lead Bronze: The third layer comes with an anti-seizing property. It is made of lead bronze. This layer is great at preventing parts from sticking together. In the setup, it is the main part th...
