Tianjin Uranus Hydraulic Machinery Co., Ltd. offers custom hydraulic cylinders that are designed for ease of integration and maintenance. We understand that a cylinder is a critical component of your machine, and we design it to fit seamlessly and be easily serviced. Our custom designs include features that simplify installation, such as integrated manifolds for direct valve mounting, and we provide detailed CAD models to facilitate machine design. For maintenance, we design with features such as removable gland nuts, replaceable wear strips, and cartridge-type seals that can be replaced without fully disassembling the cylinder. We also offer cylinders with test points and lubrication ports to facilitate condition monitoring and maintenance. Our technical support team is available to assist with integration and service questions. For a custom hydraulic cylinder that is easy to install and maintain, our designs are built for practicality. To discuss your integration and maintenance requirements, please contact us.

Frequently Asked Questions

What makes your metallurgical hydraulic cylinders suitable for steel mills?

Our metallurgical hydraulic cylinders are specifically engineered for the extreme conditions found in steel mills and foundries. They feature robust construction with thick-walled tubing, heavy-duty rod ends, and high-temperature seals that maintain integrity in ambient temperatures exceeding 200°C. We use induction-hardened, chrome-plated rods for wear resistance, and offer ceramic coatings for applications with extreme abrasion from scale. Corrosion-resistant options are available for water-intensive environments. These cylinders are designed for continuous operation, high shock loads, and long service life in demanding mill applications.
Tianjin Uranus has over 30 years of experience serving the metallurgical industry. We have supplied hydraulic cylinders and systems to steel mills and foundries for applications such as continuous casting, rolling mills, furnace equipment, and shears. Our products are designed to withstand the extreme conditions of this industry, including high temperatures, shock loads, and pervasive contamination. We understand the critical need for uptime in steel production and engineer our solutions for maximum reliability and serviceability in mill environments.
We support product maintenance and repair through comprehensive documentation, spare parts availability, and technical assistance. Our cylinders and systems are designed with serviceability in mind, featuring removable gland nuts, replaceable wear strips, and cartridge-type seals that can be serviced without full disassembly. We provide detailed maintenance manuals and can offer on-site training for your maintenance teams. Our technical support team is available to assist with troubleshooting, and we maintain a global spare parts inventory to support quick repairs and minimize downtime.
Yes, we specialize in upgrading and retrofitting existing hydraulic equipment. Our team can assess your current machinery and recommend modernizations to improve performance, energy efficiency, or reliability. This may include replacing outdated hydraulic systems with energy-efficient servo-driven systems, upgrading cylinders with integrated feedback for better control, or installing new hydraulic power units. We design retrofit solutions to integrate with your existing mechanical structure and control systems, minimizing downtime and maximizing the return on your investment.

Customer Reviews

James Wilson

We needed a custom hydraulic cylinder for a marine application that would withstand saltwater corrosion. Tianjin Uranus designed a cylinder with stainless steel components and special coatings that has performed exceptionally well in the harsh marine environment. The cylinder has been deployed for over 18 months with no signs of corrosion or wear. The Uranus engineering team was knowledgeable about marine applications and provided a solution that met all our requirements. I am very satisfied with the quality and durability of this custom cylinder.

Dr. Thomas Schmidt

Our servo hydraulic system requires a custom cylinder with very tight tolerances and low friction. Tianjin Uranus designed a cylinder with precision-ground components and low-friction seals that delivers exceptional performance. The cylinder features integrated LVDT feedback for precise position control. The Uranus team worked closely with us to ensure the cylinder met our dynamic performance requirements. The cylinder has been operating reliably in our servo system for over two years. The engineering and manufacturing quality is top-notch.
