Features
Description
Series: RT | Product Line: Industrial Tools
-
High Eccentric Load CapacityCapable of handling an eccentric load of up to 4% at maximum rated capacity, ensuring stable and safe operation even when the load is not perfectly centered on the cylinder axis.
-
Nitrided Stop RingThe nitrided stop ring effectively absorbs eccentric loads and limits plunger overstroke, preventing internal damage and enhancing operational safety.
-
Gas-Nitrided Piston RodThe piston rod undergoes a gas nitriding process, providing excellent wear resistance, corrosion resistance, and self-lubricating properties for smoother operation and extended service life.
-
Wiper SealA built-in wiper seal prevents external contaminants (dust, dirt, debris) from entering the cylinder cavity, reducing the risk of internal contamination and mechanical damage.
-
High-Pressure Sealing SystemEquipped with high-pressure seals, the RT Series achieves zero leakage in the hydraulic system, minimizes wear, and significantly extends the service life of the cylinder.
-
Low Closed HeightThe compact, low-profile design allows for easy installation in space-restricted environments, maximizing lifting efficiency while minimizing the required clearance.
-
Gas-Nitrided and Post-Oxidized Cylinder BodyThe cylinder body is treated with a gas nitriding and post-oxidation surface process, delivering superior corrosion resistance for reliable performance in harsh or humid environments.
-
Standard CEJN Quick CouplerEach cylinder comes standard with a CEJN quick coupler, enabling fast, secure, and spill-free connection to compatible hydraulic systems.
-
Integrated Tilt Saddle (Up to 5°)All RT Series cylinders are equipped with a one-piece integrated tilt saddle, allowing a maximum tilt angle of up to 5 degrees. This feature helps maintain full contact between the cylinder and the load surface under angled or uneven conditions, improving stability and reducing the risk of side loading.
