Tianjin Uranus: Leading the Way in Telescopic Cylinder Manufacturing

At Tianjin Uranus, we take pride in our expertise in manufacturing telescopic cylinders. Composed of multiple nested piston cylinders, our telescopic cylinders can achieve multi - stage telescopic motion, featuring a long stroke when extended and a compact size when retracted. They are ideal for applications where large stroke lengths are required but installation space is limited, such as in fire truck ladders, crane booms, and truck body lifting systems. We use high - quality materials and advanced manufacturing techniques to ensure the performance and longevity of our telescopic cylinders.

Why choose us?

Space - Saving Design of Telescopic Cylinders

Our telescopic cylinders stand out for their space - saving design, featuring multiple nested piston tubes for extended stroke and compact retraction. This design is ideal for applications with limited installation space, such as fire truck ladders, crane booms, and truck body lifting. We optimize space utilization without compromising performance.

High - Strength Construction for Telescopic Cylinders

We construct our telescopic cylinders with high - strength materials to withstand heavy loads and harsh conditions. The robust design resists deformation and wear, ensuring reliable performance in outdoor and industrial environments. This durability translates to reduced maintenance costs and increased equipment uptime for our customers.

Tailored Solutions for Telescopic Cylinder Applications

Understanding that each application has unique requirements, we provide tailored solutions for telescopic cylinder applications. Our engineers work closely with customers to design cylinders that match specific stroke lengths, pressure ratings, and environmental conditions. This personalized approach ensures optimal performance and customer satisfaction.

Our telescopic cylinders with synchronous extension mechanisms utilize a gear-rack synchronization system to ensure uniform stage movement (deviation ≤0.3 mm). The system incorporates a precision-machined rack (module 2, grade 6) and pinion gear (20CrMnTi, carburized to 60 HRC), which maintains synchronization under varying loads. High-strength alloy steel barrels (40CrNiMoA, yield strength ≥980 MPa) and bronze wear bands provide lateral load resistance, while internal check valves with pilot-operated relief ensure safe retraction. This design is ideal for fire truck ladders (up to 15-story reach), crane booms, and mobile platforms, with stroke lengths up to 18 meters. The synchronous mechanism reduces stress on the hydraulic system by 30%, extending component life.

Frequently Asked Questions

What is the working principle of a telescopic cylinder?

A telescopic cylinder consists of multiple nested piston cylinders. When hydraulic oil is supplied, the outermost cylinder extends first, followed by the inner cylinders in sequence, achieving a long - stroke extension. During retraction, the process is reversed, and the cylinders retract one by one, resulting in a compact size when retracted.
Compared to ordinary cylinders, telescopic cylinders can achieve a much longer stroke within a limited space. They are also more flexible in terms of installation and can adapt to different working conditions where space is restricted, while still providing sufficient force for the operation.
Regularly check for oil leakage at the joints of each cylinder section and replace the seals in time if there is leakage. Clean the outer surface of the cylinder to prevent dirt and debris from entering the cylinder. Also, check the hydraulic oil level and quality regularly and perform oil changes as required.
Yes, the company can provide telescopic cylinders with special requirements, such as customized stroke lengths, high - pressure resistance designs, and special materials for use in harsh environments, to meet the diverse needs of customers in different industries.

Customer Reviews

Kevin White

The telescopic cylinders from Tianjin Uranus have been a game-changer for our fire truck manufacturing. The ability to achieve a long stroke while maintaining a compact retracted size is exactly what we needed for our aerial ladder designs. The multi-stage extension is smooth and reliable, even at full extension. The build quality is exceptional, and we've had no issues with leakage or mechanical failure. Highly recommended for applications with space constraints.

Nancy Parker

When we needed a unique telescopic cylinder for a special project, Tianjin Uranus' customization service was outstanding. Their engineers worked closely with us to design a cylinder that met our specific stroke and pressure requirements. The technical support during the installation and testing phases was invaluable. The cylinder has performed flawlessly, and we're impressed with the level of expertise and attention to detail provided by the team.
