Hitachi Excavator Parts EX1900 Hydraulic Cylinder 4456959

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.

Innovatively equipped with an adaptive buffer device, it can effectively absorb impact energy and reduce mechanical vibration during excavation operations, without compromising excavation force or reducing work efficiency. What's more considerate is that it supports the installation of a buffer regulating valve core, allowing users to fine-tune the buffer effect in real time according to their actual operating habits and working conditions, making the operation experience more in line with expectations.

By optimizing the structure of the traditionally vulnerable parts of the hydraulic cylinder, combined with stress dispersion design and special surface treatment processes, the failure rate is reduced at the source. Throughout its entire life cycle, the product maintains a high level of operational stability, providing solid protection for the continuous operation of the equipment and reducing losses caused by shutdowns for maintenance.
