Product introduction
This Cummins crankshaft thrust (part number 3691445) is a core component of the engine crankshaft system, specifically designed to withstand axial loads and ensure stable crankshaft operation. Made of high-strength alloy steel and featuring metal-rubber composite sealing technology, this crankshaft thrust is compatible with Cummins QSX15 series heavy-duty engines, offering high load-bearing capacity, high-temperature resistance, and impact resistance. Its optimized contact surface structure distributes axial loads, reducing crankshaft wear. Cummins main bearings also precisely match crankshaft and connecting rod tolerances to minimize vibration and noise. Widely used in construction machinery, mining vehicles, and generator sets, it is recommended to inspect and maintain it every 5000 hours.
