Big end bearing shell, upper 0.5 mm.

The spare part 111006, known as the "big end bearing shell," is a critical component used in the Wärtsilä 20 engine.

Function and Importance:

Connection Point: The big end bearing shell is part of the connecting rod assembly in the engine. It serves as the bearing surface between the connecting rod and the crankshaft's big end (also known as the crankpin).

Load Bearing: It supports the crankshaft's rotational movement and the reciprocating motion of the connecting rod. This bearing surface must withstand high mechanical stresses and ensure smooth operation.

Reduction of Friction: The bearing shell is typically made from a material that reduces friction and withstands high temperatures and pressures. This reduces wear on both the connecting rod and the crankshaft, extending their operational life.

Alignment and Stability: Proper installation and maintenance of the big end bearing shell are crucial for maintaining alignment and stability between the connecting rod and the crankshaft. This alignment ensures efficient power transmission and minimizes vibration.

Maintenance and Replacement: Like other engine bearings, the big end bearing shell requires periodic inspection and maintenance. If signs of wear, scoring, or damage are detected during routine checks, the bearing shell may need to be replaced to prevent engine damage and maintain performance.
