Turbocompresseur Komatsu SAA6D114E-3 HX40W pour excavateur Komatsu PC300-8, PC350-8, and PC400-8

Applicable Models: Komatsu SAA6D114E-3 series diesel engines.

Compatible Equipment: Major Komatsu large excavator series, including the PC300-8, PC350-8, and PC400-8.

Housing Material: Cast from ultra-high-strength, heat-resistant nickel-chromium alloy. Optimized for heavy-duty exhaust environments, the housing effectively withstands extreme thermal fatigue and pressure shocks, ensuring long-term durability and crack resistance.

Core Impeller: Features a lightweight, hydrodynamically optimized impeller with precision dynamic balancing. It delivers superior aerodynamic response, ensuring rapid and constant intake pressure during heavy-load excavation.

Bearings and Seals: Equipped with high-performance floating bearing sets capable of withstanding radial loads at high speeds over extended periods. High-specification sealing components effectively prevent oil leakage, maintaining optimal cleanliness within the combustion chamber.

Dynamic Balancing: Every unit undergoes rigorous high-speed VSR (Vibration Sorting Rig) dynamic balancing tests before leaving the factory. This eliminates micro-vibrations during operation, extending the turbocharger's lifespan and ensuring exceptionally smooth, quiet performance.

Installation Compatibility: Manufactured in strict accordance with Komatsu OE technical standards. Intake ports, exhaust flanges, and oil line connections are precision-matched for "plug-and-play" installation, significantly reducing maintenance downtime.
