Engine block parts are essential components that ensure the structural integrity and performance of a vehicle's engine. Crankshaft and rod parts play a critical role in converting the linear motion of the pistons into rotational motion, providing the necessary power for movement. Cooling parts are vital for maintaining optimal operating temperatures, preventing overheating, and enhancing engine efficiency. Air intake and exhaust parts facilitate proper airflow, ensuring effective combustion and exhaust expulsion, which ultimately improves engine performance. Fuel injection parts deliver the precise amount of fuel needed for efficient combustion, while electrical parts ensure reliable functionality throughout various systems in the vehicle. Additionally, filters play a crucial role in maintaining engine health by preventing contaminants from entering crucial components, promoting longevity and performance.

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.
Fuel pumps for NT855, K19, K38 and K50 are core components of the Cummins engine lineup covering various displacements and application scenarios. Though all built on the classic PT fuel system principle, they differ in design, materials and technical details to meet diverse operating demands ranging from construction machinery and large mining equipment to generator sets.
The Cummins QSL9 / ISLe Series Fuel Pipes are essential components designed for efficient fuel delivery in Cummins QSL9 and ISLe engines. Engineered for durability and reliability, these fuel pipes ensure optimal engine performance and fuel efficiency, making them vital for heavy-duty applications.
As the "heart component" of diesel engines, the atomization quality and injection precision of fuel injectors directly determine the overall power output, fuel economy and emission performance of the whole machine. We supply OEM-grade fuel injector assemblies and precision matching parts covering the full lineup of Cummins engines including NT855, M11, QSX15 and K-series. Superior manufacturing craftsmanship sustains peak performance of your equipment.

Cummins piston cooling nozzles act as invisible guardians of the engine lubrication and cooling system, custom-designed for NT855, M11, K19, K38, K50 and other series engines.During high-load engine operation, the temperature of piston crowns can exceed 300°C. With precise positioning, cooling nozzles inject high-pressure engine oil directionally to the piston underside or internal piston cooling galleries to forcibly dissipate heat. This prevents piston thermal deformation, cylinder scuffing and even crown ablation.As mandatory wearable parts for engine overhaul, their injection angle, opening pressure and high-temperature resistance directly determine engine service life and operational stability.
Cummins High-Horsepower Engine Pistons are meticulously engineered components designed to enhance the performance and durability of heavy-duty engines. Built to withstand extreme pressures and temperatures, these pistons ensure optimal efficiency and reliability for demanding applications in industries such as transportation, agriculture, and construction.
Cummins Full Series Engine Connecting Rods are precision-engineered components designed to optimize engine performance and durability in Cummins engines. Crafted from high-strength materials, these connecting rods ensure reliable power transfer and enhanced longevity, making them essential for maintaining engine efficiency and reliability in demanding applications.
Cummins NT855 crankshaft is a core transmission component engineered for NT855 series heavy-duty diesel engines, compatible with Shantui TY230 bulldozers, Yishan TY200 bulldozers, mining dump trucks and various stationary generator sets. As the central power-output shaft of the engine, it is integrally forged from high-strength alloy steel, followed by quenching and tempering treatment plus induction hardening on journal surfaces to reach a hardness of HRC55–60. It boasts outstanding fatigue resistance and wear resistance, capable of enduring bending and torsional stress generated during long-term high-load operation (torque range: 1420–1790 N·m), serving as an essential foundational part to sustain continuous and efficient equipment performance.
With 20 years of extensive experience in the sales and maintenance of Cummins engines and parts, we provide robust power solutions ranging from 175HP to 2500HP. Our core product lineup includes the NTA855, KTA19, KTA38, KTA50, QSK60, and M11 series.
