Hi-Force Portable General Purpose Hydraulic Cylinder Single Acting 4.5 Ton 125 mm Stroke, HSS55

Hi-Force HSS55 Portable General Purpose Hydraulic Cylinder is engineered for demanding industrial lifting and pushing applications requiring flexibility and reliability. With a single acting spring return design, the HSS55 delivers a robust 4.5 ton capacity and a stroke length of 125 mm, making it suitable for mining, power stations, railways, shipyards, steelworks, and other heavy-duty environments.

Designed for frequent high cycle operations, this cylinder features non-metallic bearings on the piston rod and stop ring, offering exceptional wear resistance and low friction. The piston rod is chrome plated to prevent corrosion, while pressure-activated anti-extrusion seals enhance performance and extend service life. Heavy-duty return springs enable the piston to retract fully, ensuring consistent operation and readiness for subsequent tasks.

High-strength alloy steel construction provides a minimum safety factor of 3:1, addressing rigorous safety standards in critical applications. Steel stop rings enhance the cylinder’s side load capacity and maintain piston integrity at full extension. All port connections are standardized at 3/8 inch NPT, with each unit equipped with a high flow quick-release female half coupler to streamline hydraulic integration.

The cylinder operates at a maximum pressure of 700 bar and includes an effective area of 14.4 cm², with an oil capacity of 80 cm³. Its compact dimensions (closed height 207 mm, extended height 332 mm, outside diameter 38 mm) and gross weight of 1.8 kg make it easy to handle and transport.

This engineered solution is ideal for industrial maintenance, manufacturing, construction, and plant operations. Service and repair seal kits are available to extend operational life and minimize downtime. When used with compatible high-pressure hydraulic hand pumps, it guarantees reliable performance in any environment where robust lifting and pushing force are needed.
