Features
Description
Series: RLT | Product Line: Industrial Tools
-
Single-Acting, Load ReturnThe RLT Series operates with single-acting hydraulic advance and load return, simplifying the hydraulic circuit while ensuring reliable retraction under load.
-
Advanced Surface TreatmentCylinder components undergo gas nitriding and post-oxidation surface treatment, providing:
-
Superior corrosion resistance
-
Enhanced resistance to eccentric loads
-
Increased surface hardness for extended service life
-
-
Ideal for Confined SpacesThe low height design makes the RLT Series particularly suitable for applications with limited vertical clearance, including equipment positioning and tool fixing.
-
Mounting Bolt Holes for Easy FixationPre-drilled mounting bolt holes allow for simple and secure attachment to fixtures, machinery, or work surfaces, ensuring stable operation during use.
-
High Eccentric Load CapacityCapable of withstanding an eccentric load of up to 3% at full rated capacity, providing stable and safe performance even when the load is not perfectly centered.
-
High-Strength Alloy Steel ConstructionManufactured from high-strength alloy steel, the RLT Series guarantees exceptional service life and reliable performance under demanding working conditions.
