Cummins gear housings are core transmission and sealing components custom-designed for K-series high-power diesel engines, covering K19 (19L), K50 (50L) and NT855 series models. Serving as the "power distribution hub" of the engine, the gear housing is integrally cast from high-strength alloy cast iron. It internally accommodates crankshaft gears, camshaft gears, fuel pump gears and multiple idler gears.
The Cummins cylinder liner series is engineered to meet demanding engine performance requirements in harsh operating conditions, covering a wide range of applications from construction machinery to heavy-duty mining equipment and power generation units.
The Cummins engine cylinder head serves as the "head" core component of the power system, responsible for sealing the combustion chamber, guiding intake and exhaust flow, and transferring heat. The entire series is cast from high-strength alloy cast iron, featuring excellent heat resistance, sealing performance, and heat dissipation capabilities to ensure stable engine operation under heavy loads.
The Cummins engine cylinder block serves as the "skeleton" and core foundation of the power system. Engineered for medium and heavy-duty construction machinery, generator sets, marine propulsion, and mining equipment, the entire series is integrally cast from high-strength alloy iron. It delivers outstanding rigidity, vibration resistance, and durability, ensuring stable power output even under extreme operating conditions.
