Hitachi Excavator Parts EX1900 Hydraulic Cylinder 4478058

The main body of the hydraulic cylinder is constructed from high-strength materials, combined with customized heat treatment processes and precision welding technologies, endowing the product with excellent anti-fatigue properties. Even when operating continuously under harsh conditions of extreme high pressure and heavy loads, it can maintain long-term and stable performance, significantly extending the service life of the equipment.

Thanks to its special structural design, the hydraulic cylinder can work stably within a wide temperature range from -40°C to +120°C, easily coping with diverse operating environments such as severe cold and high temperatures. For scenarios with special temperature requirements, we can also provide exclusive customized solutions to ensure that the equipment's performance is not affected by extreme climates.

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.
