Турбокомпрессор Komatsu 6D125 KTR85V-33VRW для строительной техники

Compatible Models: Komatsu S6D125 / SA6D125 / SAA6D125 series diesel engines.

Applicable Equipment: PC400-6/7 and PC450-6/7 excavators, D85 and D155 bulldozers, and various heavy-duty industrial units.

Housing Material: Crafted from high-grade, heat-resistant alloy cast iron. The housing thickness and heat-dissipation structure are specially reinforced to withstand the thermal expansion pressures caused by extreme exhaust temperatures in environments like mines, ensuring the casing remains free from deformation or cracking during long-term use.

Core Impeller: Features a high-efficiency impeller optimized via precision fluid dynamics. With extremely low rotational inertia, it significantly improves engine power response during high-load transitions, eliminating power lag.

Precision Dynamic Balancing: Undergoes rigorous high-speed dynamic balancing checks before leaving the factory. This ensures smooth, quiet operation at rated high speeds, effectively reduces bearing vibration, and substantially extends the service life of both the turbocharger and the engine.

Sealing Reliability: Equipped with high-performance floating bearings and a reinforced sealing system. This effectively prevents oil leakage into the intake tract, averts issues such as blue smoke and oil burning, and ensures the combustion chamber remains clean and efficient over the long term.

Installation Fit: Manufactured in strict accordance with Komatsu OE standards. Oil inlet/outlet ports, exhaust flange dimensions, and mounting brackets match perfectly, ensuring a "plug-and-play" installation that saves significant maintenance time.
