Hitachi Excavator Parts EX1900 Hydraulic Cylinder 4478057

Our hydraulic cylinders are crafted from high - strength materials. Paired with specialized heat treatment and welding techniques, they exhibit an outstanding fatigue endurance. This means they can operate under extreme high - pressure and heavy - load conditions, maintaining a long - term and reliable service life.

Engineered to function across a broad temperature spectrum from - 40°C to +120°C, our hydraulic cylinders are suitable for diverse environments. Moreover, we offer customized solutions for applications with more demanding temperature requirements.

Equipped with an innovative buffer design, our cylinders minimize shock during excavation operations. This is achieved without sacrificing the excavation force or hampering work efficiency. What's more, customers can opt to add a buffer regulating valve core. This allows for real - time adjustment of the buffer effect, tailored to their specific operating experiences.

We've identified and optimized the design at common failure - prone points of hydraulic cylinders. By reducing stress concentrations and applying special process treatments, we ensure the utmost reliability and stability throughout the product's lifespan.
