MAN B&W 6L42MC Main bearing
A main bearing is a critical component in a piston engine that supports the crankshaft and allows it to rotate smoothly within the engine block. They are located in the crankcase and are typically made of two semi-circular shells, with an upper and lower half that hold the crankshaft in place.
Construction and Materials
Two-part design: Most main bearings are composed of two halves, an upper and a lower shell, which are installed in the crankcase and held in place by bearing caps.
Oil passages: The upper half of the bearing often has an oil groove, and a hole for passing oil to the crankshaft's feed holes is included.
Materials: Common materials include bronze, aluminum alloys, steel, and bi-metal combinations.
Coating: A thin flash of tin or lead-tin is applied to the bearing bore for corrosion protection before installation.
