Why choose us?

Built for Long Life with Advanced Sealing Systems

We ensure the longevity of our high pressure hydraulic cylinders with advanced sealing systems. These seals are specifically chosen to withstand extreme pressures and temperatures, preventing fluid loss and contamination ingress to ensure consistent performance and a long service life.

Compact, High Power Density Designs

Our high pressure hydraulic cylinders are designed to deliver immense force from a compact package. This high power density makes them perfect for applications with limited installation space, such as clamping units, tooling fixtures, and mobile equipment, without sacrificing reliability.

Expertise in Extreme Pressure Applications

As a "national small giant" enterprise, we possess deep expertise in high pressure hydraulics. Our high pressure hydraulic cylinders are engineered with advanced materials and sealing technologies to safely and reliably handle extreme pressures, making them ideal for heavy equipment, presses, and test rigs.

Tianjin Uranus Hydraulic Machinery Co., Ltd. provides high pressure hydraulic cylinders with integrated smart features that enable condition monitoring and predictive maintenance. As a leader in integrated mechanical-hydraulic-optical intelligent equipment, we embed sensors into our high pressure cylinders to provide real-time data on pressure, temperature, and, if required, position. This data can be used to monitor the health of the cylinder and the system. For example, a sudden increase in temperature or a change in pressure profile can indicate seal wear or other developing issues, allowing for proactive maintenance before a failure occurs. We can also integrate acoustic emission sensors to detect early signs of material fatigue or cracking. The data from the cylinder can be transmitted to a central control system or to the cloud for analysis, enabling a predictive maintenance strategy. Our smart cylinders can also be equipped with RFID tags that store key parameters, such as serial number, pressure rating, and maintenance history, facilitating asset management. For a high pressure hydraulic cylinder that not only performs reliably but also helps you anticipate and prevent problems, we invite you to contact us to discuss the possibilities.

Customer Reviews

Jennifer Lee

We required a high pressure hydraulic cylinder with integrated position feedback for a precision forming application. Tianjin Uranus designed a cylinder with a built-in magnetostrictive sensor that provides accurate position data for closed-loop control. The cylinder operates at 700 bar and delivers precise, repeatable motion. The quality of the machining and assembly is excellent. The Uranus team provided thorough documentation and support. This cylinder has been critical to achieving the precision we need for our manufacturing process.

Dr. Peter Chen

Our component test rig requires high pressure hydraulic cylinders that can deliver up to 10,000 psi for burst and fatigue testing. Tianjin Uranus supplied cylinders that have been operating reliably for over two years. The cylinders are built with forged components and feature redundant sealing systems that have prevented any leaks. The precision machining ensures smooth operation, and the integrated pressure sensors provide accurate data. The Uranus team provided excellent support and documentation. These cylinders are critical to our testing capabilities.
