RA554 50 Ton Single Acting Cylinder Spring Return Hydraulic Cylinder 4 in Stroke

The Power Team RA554 is a 50-ton, single-acting, spring-return hydraulic cylinder with a 4 in stroke, engineered for high-force lifting, pressing, and maintenance operations. Rated to 10,000 psi, it delivers precise, repeatable force through a precision-ground alloy steel body and piston assembly. The Power-Tech surface treatment maximizes resistance to wear and corrosion, ensuring durability in demanding industrial and field conditions. Hydraulic extension with automatic spring retraction simplifies circuit design and provides fast return for efficient single-line operation.

Compact, rigid, and performance-driven, the RA554 excels in applications such as die separation, press fitting, and heavy equipment alignment. Its low-profile build minimizes deflection under load, while the standard 3/8 in NPTF port integrates seamlessly with Power Team pumps and accessories. Designed for sustained reliability in repetitive duty cycles, the RA554 offers exceptional force density, stability, and operational efficiency—making it a preferred choice for precision hydraulic systems where compact power and consistent control are critical.

Use Cases

The RA554 is engineered for medium- to heavy-duty industrial applications requiring high load capacity with a straightforward, compact hydraulic setup. Typical operations include equipment maintenance, die separation, press fitting, and structural alignment tasks where consistent force output and dependable retraction are essential. Its spring-return configuration makes it well-suited for vertical lifting or repetitive-cycle work where automatic piston return improves efficiency. The RA554 is also frequently used in maintenance pits, fabrication shops, and production lines for lifting or pushing components under limited clearance conditions.

Advantages

The RA554 provides a high power-to-size ratio, combining 50 tons of output with compact geometry and a 4 in stroke. The single-acting, spring-return design reduces hydraulic circuit complexity and ensures quick retraction without the need for external flow control. The Power-Tech surface treatment increases service life by enhancing resistance to corrosion and mechanical wear. Precision-ground piston and seal assemblies minimize internal friction, maintaining consistent performance across pressure cycles. The standardized 3/8 in NPTF port ensures system compatibility with most 10,000 psi Power Team pumps and accessories, simplifying integration into existing setups.

Safety and Maintenance Considerations

The RA554 must be used exclusively with hydraulic systems rated for 10,000 psi and fitted with compatible hoses and couplings. Cylinders should always be placed on a stable, level surface with full piston contact to prevent misalignment or side loading, which can cause seal damage or housing deformation. Off-center loading should be avoided, and the load should be applied along the cylinder axis to ensure uniform stress distribution. Operators should verify that the return spring is not obstructed during retraction and that the cylinder is not used in applications exceeding its rated capacity or stroke limits.

Routine inspection is essential for maintaining safe and reliable operation. The cylinder should be checked regularly for leaks, damaged threads, or worn seals, and all hydraulic fluid should remain clean and filtered to prevent contamination. Light lubrication of exposed surfaces and proper storage in a clean, dry environment will extend service life. Servicing and internal disassembly should be performed only by qualified personnel, as the internal spring retains stored energy and may present a safety hazard if improperly handled.
