Hydraulic cylinders for construction equipment need to be robust, enduring, and reliable. Our components are meticulously engineered to withstand the rigorous demands of challenging environments, thereby reducing costly downtime and minimizing maintenance concerns. Rely on our durable solutions to keep your projects moving forward seamlessly.
Production Process:
Our meticulous production process guarantees excellence: Begin with superior material selection → Proceed to precision tempering → Utilize cylindrical lathe cutting → Employ high-frequency quenching → Execute cylindrical grinding → Apply hard chrome plating → Conclude with external grinding.
After undergoing tempering and high-frequency surface quenching, our components feature an exterior adorned with a hard chrome finish, delivering exceptional durability.
This advanced treatment results in an ultra-hard surface both internally and externally, each polished to a seamless and smooth finish of the highest standard.
