Construction Machinery Diesel KTA19 Engine Crankshaft 3418898

Our crankshaft is designed for a critical mission: to precisely convert piston reciprocating motion into powerful rotational force. Crafted from high-quality alloy steel, it undergoes both precision forging and stringent heat treatment. This process gives it exceptional fatigue strength and outstanding wear resistance. As a result, it delivers absolute reliability even under high-load conditions.We employ advanced dynamic balancing technology and high-precision CNC machining in its production. This effectively eliminates excessive vibration and noise. At the same time, we achieve micron-level accuracy on key surfaces such as the journals.These engineering optimizations ensure exceptionally smooth and quiet engine operation. They also maintain optimal bearing clearance, which significantly reduces friction losses. Consequently, fuel economy is effectively improved, and the engine’s overall service life is extended.
