Precision Hydraulic Press Ram | Custom Stroke & Tonnage

Tianjin Uranus Hydraulic Machinery Co., Ltd. manufactures precision hydraulic press rams that are the core actuation component in forming, stamping, and forging presses. As a “national high-tech enterprise” with over 30 years of experience, we engineer these rams to deliver smooth, accurate force transmission with minimal deflection, ensuring consistent part quality and extended tool life. Our hydraulic press rams are constructed from high-strength alloy steel, forged or fabricated, and precision-machined to exacting tolerances. The ram is guided by heavy-duty, adjustable gibs or a precision-machined frame to ensure accurate alignment throughout the stroke, even under eccentric loads. The piston is induction-hardened and chrome-plated for wear resistance, and we use high-quality seals designed for high-cycle operation. We also offer rams with integrated position feedback, such as linear encoders or magnetostrictive sensors, enabling precise closed-loop control of position and speed. For applications requiring high-speed operation, we design the ram with optimized mass and porting to achieve rapid response. Our manufacturing process includes non-destructive testing and dimensional inspection to ensure structural integrity. Each ram is tested for functionality and leak-free operation before delivery. For a hydraulic press ram that provides the precision and durability your forming process demands, we encourage you to contact us to discuss your specific requirements.
