Power Team offers solutions to overcome your heavy lift challenge with over 96 years of experience

RSS502 50 Ton Single-Acting Cylinder Spring-Return Hydraulic Cylinder 2 in Stroke

The Power Team RSS502 is a 50-ton, single-acting, spring-return hydraulic cylinder with a 2 in stroke, built for high-force performance in confined or portable applications. Operating at 10,000 psi, it delivers precise, repeatable output through a precision-machined alloy steel body and piston assembly protected by Power-Tech surface treatment for superior wear and corrosion resistance. Hydraulic extension and spring-assisted retraction streamline system design, ensuring fast, efficient cycle times in demanding service conditions.

Compact, rugged, and performance-focused, the RSS502 is ideal for lifting, pressing, and alignment operations in maintenance, fabrication, and construction environments. Its short stroke enables controlled, high-force movement for tasks such as die separation, bearing installation, and heavy equipment positioning. Engineered for reliability under repetitive loads, the RSS502 integrates seamlessly with Power Team pumps and accessories, providing consistent force delivery and long service life in critical hydraulic applications.

Use Cases

The RSS502 is suitable for precision lifting, alignment, and pressing applications in maintenance, production, and structural support environments. It is frequently used in heavy equipment service, steel fabrication, die handling, and general plant repair where compactness and portability are key. Its spring-return design enables rapid retraction between cycles, improving productivity in repetitive load operations. The cylinder’s construction supports both vertical and horizontal use, making it adaptable for field repair, construction alignment, and small press systems requiring dependable force in a short-stroke configuration.

Advantages

The RSS502 offers a high power-to-size ratio, producing 50 tons of output within a compact 6.38 in collapsed height. The single-acting, spring-return configuration simplifies hydraulic system requirements while providing automatic piston retraction for faster operation. The Power-Tech treated alloy steel body enhances resistance to corrosion and mechanical wear, extending operational life in harsh industrial conditions. Precision-engineered seals and piston surfaces ensure minimal friction and consistent performance under repeated high-pressure cycles. Its standard 3/8 in NPTF porting allows seamless integration with Power Team pumps and accessories, and the robust design ensures stability, repeatability, and long-term reliability in demanding applications.

Safety and Maintenance Considerations

The RSS502 must be operated only with hydraulic systems rated for 10,000 psi to ensure safe and consistent performance. Before each use, all hoses, fittings, and couplers should be inspected for proper connection, rated pressure compatibility, and absence of damage or leaks. The cylinder should always be positioned on a solid, level surface with full base contact to prevent instability or uneven load transfer. Off-center loading must be avoided, as lateral forces can cause premature seal wear, rod scoring, or housing distortion. The cylinder’s spring-return mechanism should never be obstructed; ensure that the piston can fully retract without interference. During multi-cylinder operations, maintain proper load synchronization and use control valves designed for balanced flow to avoid pressure spikes or uneven lifting.

Routine inspection and preventive maintenance are essential for maintaining operational integrity. Hydraulic oil must remain clean and free of contaminants—dirty or degraded fluid can damage seals and internal surfaces. Inspect piston rod and seal areas regularly for signs of corrosion, scoring, or leakage, and lightly lubricate exposed metal surfaces to prevent oxidation. Never exceed the rated stroke or pressure, and avoid mechanical shock loading. When not in service, store the RSS502 fully retracted in a clean, dry environment. Any internal servicing or disassembly should be carried out only by qualified technicians, as improper handling of the internal spring or hydraulic components may result in equipment damage or personal injury.
