RCS302, 30 Ton Capacity,62mm Stroke, Low Profile Hydraulic Cylinders
Designed for confined spaces and demanding applications, the RCS Series from RIVERLAKE delivers reliable performance in a lightweight, compact body. These single-acting, spring-return cylinders combine advanced surface treatment with practical features to ensure durability, corrosion resistance, and ease of use in industrial and construction environments.
Description
Series: RCS | Product Line: Industrial Tools
Key Features:
-
Advanced surface treatment – Cylinder body, piston, and stop ring undergo gas nitriding + post‑oxidation, providing excellent wear resistance, self‑lubrication, and corrosion protection.
-
Additional paint finish – The entire cylinder receives a second paint coating, enhancing visual identification and further improving corrosion resistance.
-
Compact & lightweight design – Ideal for working in tight spaces where full‑size cylinders cannot fit.
-
Wiper seal – Minimizes contamination ingress, significantly extending hydraulic cylinder service life.
-
Standard CEJN quick coupler & dust cap – All models are equipped with a genuine CEJN quick coupler and protective dust cap for fast, clean connections.
-
Threaded plunger top – The grooved plunger features a threaded hole at the top, allowing easy mounting of an optional tilt saddle.
-
Portable option – Model RCS‑1002 comes with a built‑in handle for convenient carrying.
-
Single‑acting, spring return – Reliable spring retraction simplifies operation and improves safety.
Design
- Dust seal, preventing external impuritiesfrom entering the interior of the cylinder and causing contamination or damage.
- The piston rod adopts gas nitriding treatment,featuring excellent wear resistance and corrosion resistance.
- The Swedish CEJN coupler and dust cap ensure safety throughout.
- The gas-nitrided stop ring is used to absorb eccentric load and prevent plunger over-travel.
- The cylinder body is treated by gas nitriding plus post-oxidation process,followsed by external baked painting to deliver superior corrosion resistance
- High-pressure seal to achieve zero internal leakage in the hydraulic system, reducing wear and extending service life.
- Powerful spring for rapid return stroke.
