Export Qsc8.3 Engine Manufacturers – Cummins Engine Part Connecting Rod Bearing 4096915/4097343 For Cummins QSK23 Engine – Raptors

Product Parameter

The crank connecting rod mechanism is the main moving part of the engine to realize the working cycle and complete the energy conversion. It consists of a body, a piston connecting rod, a main shaft, a connecting rod bush and a crankshaft flywheel. In the work stroke, the piston bears the gas pressure and moves linearly in the cylinder, which is converted into the rotational movement of the crankshaft through the connecting rod, and outputs power from the crankshaft, while the bearing bush finally bears the maximum load. In the intake, compression and exhaust strokes, the flywheel releases energy and converts the rotational motion of the crankshaft into linear motion of the piston.

The car’s large and small bushes are actually the bearing bushes, which are divided into crank bushes and connecting rod bushes. They are made of high-hardness and wear-resistant steel. They are divided into two pieces, which are attached to the crankshaft and cylinder block, and the connecting rod and crankshaft. There are oil inlet holes on the bearing bush. When the engine is running at high speed, the oil is splashed to various parts of the engine. The oil penetrates into the oil inlet hole of the bearing bush and lubricates the bearing bush. The bearing bush is equivalent to the bearing and is responsible for the difference between the two parts on the same shaft. Direction rotation. Because of its simple structure, small size and wear resistance, the bearing shell is mostly used in the internal shaft connection of internal combustion engines.

Porduct application

Cummins engines are mainly used in commercial vehicles, construction machinery, mining equipment, marine power and generator sets, etc.
