MAN B&W 6L42MC Main bearing
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.

MAN B&W S50MC-C Connecting rod bearing
1.The connecting rod big-end bearing must withstand cyclical impact loads and frictional wear, requiring high fatigue strength and wear resistance.
2.The bearing's inner diameter mates with the crankshaft journal, while its outer diameter connects to the connecting rod small end, achieving axial positioning via a bushing.
Connecting rod bearings are usually made of alloy steel, with a circular or I-shaped main body and bronze bushings or needle bearings at both ends, and are articulated by a shaft pin.
