RLS500S – 50 Ton, Low Profile Single-Acting Hydraulic Cylinder

50 Ton Single-Acting, Spring-Return “Low Profile” Hydraulic Cylinder

The Power Team RLS500S is a 50-ton low-profile, single-acting, spring-return hydraulic cylinder designed for heavy lifting in confined spaces where clearance is limited. With a compact 2.625 in collapsed height and a 0.625 in stroke, it delivers powerful lifting force in tight applications such as machinery maintenance and structural alignment. Built for durability, its steel body, piston, and gland nut feature a “Power Tech” corrosion- and abrasion-resistant treatment. The RLS500S includes a swivel cap to reduce off-center loading, a heavy-duty internal spring for fast piston retraction, and a standard 3/8 in NPTF female half coupler for easy hydraulic connection. This rugged and reliable cylinder provides exceptional strength and performance in industrial environments where space and precision matter.

Key Advantages / Use-Case Features

Low clearance applications: Because of the very short retracted height (2.625” for this model), it’s suited to situations where you have minimal space underneath the load or structure.
Spring return: The spring return means once hydraulic pressure is released, the piston retracts automatically (rather than relying solely on gravity or external load). That makes it faster and simplifies setup.
High force in compact package: 50 tons of capacity in a very short stroke/height envelope means a high power‐to‐height ratio.
Durability: With “Power Tech” treatment to body/piston/gland for corrosion/abrasion resistance, the tool is built for heavy duty industrial use.
Single acting simplicity: Fewer hydraulic connections and less complexity compared to double‐acting cylinders, which is often desirable in lift/jack applications where extension is primary function.
Standard coupler and porting: Use of standard 3/8" NPTF coupler allows compatibility with many hydraulic hose/pump systems.

🛠 Considerations / Limitations

Limited stroke: With only ~0.625 in of extension, this cylinder is meant for very small travel or “shim” type lifts rather than large displacement operations.
Single‐acting only (spring return): The return action uses spring rather than hydraulic pressure.
Require suitable hydraulic pump and hoses: Because it’s rated up to 10,000 psi, ensure your pump and hoses are rated and safe for that pressure to achieve full capacity force.
Alignment & off‐centre loading: Although it has a standard swivel cap (for the 50‐150 ton models) to reduce off‐centre loading, you still need to ensure load is well aligned with the piston to avoid side loads and possible damage.

🔍 Typical Applications

Situations where you have to lift or push within a very shallow clearance gap (e.g., under heavy machinery, under base plates, in repair/maintenance operations).
Shim lifting or minor adjustment of heavy components Use in confined or awkward spaces where a taller cylinder couldn’t fit or where limited travel is needed.

🛠 Installation & Safety Tips

Ensure that the base of the cylinder is on a firm, level surface; low profile means less margin for misalignment.
Use the correct rated hoses, couplers, and hydraulic pump; matching the 10,000 psi spec is vital.
Avoid off‐centre loads on the piston. The specification notes effects of off‐centre loading are minimised via swivel cap for 50-150 ton models.
Inspect regularly for signs of wear, leaks, or corrosion. The corrosion/abrasion treatment helps but heavy usage in harsh environments still demands inspection.
Always adhere to manufacturer’s instructions and safety standards. Because at 50 ton force, misuse or failure can be dangerous.
