Big-end bearing assembly for MAK 16M453AK

The big-end bearing assembly, identified by part number 1.2820, is a component within the internal combustion engine assembly. It provides a bearing surface between the connecting rod and the crankshaft journal, facilitating rotational movement during engine operation. This component is designed to support the loads generated during the combustion cycle, ensuring the transmission of power from the piston to the crankshaft.

This part is compatible with the MAK 16M453AK engine model, specifically for units with serial numbers 50134 and 50135. It is part of the ATEM 1.0-3 assembly. The component maintains the mechanical integrity of the connecting rod and crankshaft interface.

Big-end bearings function by maintaining a hydrodynamic oil film between moving parts. This film separates the metal surfaces to reduce friction and heat during engine cycles. Proper fitment and clearance are necessary to ensure the continuous supply of lubricant to the bearing surface, which supports the reciprocating motion of the engine assembly.
