Non-Metallic Sleeve Marine Bearing employs our bearings in the rudder, shaft, and stern gear applications, including navy ships, cargo/container ships, trawlers, and coastal fishing boats. The main bearing is thus built to withstand a variety of forces while also supporting a revolving crankshaft. This is very easy to install and simple to handle. Non-Metallic Sleeve Marine Bearings material must be able to sustain the crankshaft journal while simultaneously adjusting to slight surface flaws. This bearing is very effective as well as economical and safe to use.
