Factory Supply Fuel Pump - Cummins Engine Part Main Bearing Set 4096907 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.

When the engine is working, the bearing bush will bear the impact force transmitted by the moving parts, can not wear adjacent parts, but also carry the maximum load, not only to ensure its own strength, but also to have good impact plastic changes, lubricating oil acidic corrosion , Electric corrosion, etc.

When the engine is working, if there is poor assembly, poor lubrication, high temperature, overload operation, etc., the bearing bush first damages itself to protect other parts and reduce the maintenance cost of the engine to a minimum. The reason why bearing bush products is also called “the fuse of the engine” in the engine industry.

Porduct application

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