Hitachi Excavator Parts EX1900 Hydraulic Cylinder 4456955

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.

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.
