Features
Description
Series: CULP | Product Line: Industrial Tools
-
High Eccentric Load CapacityCapable of withstanding eccentric loads up to 4% of maximum rated capacity. This ensures reliable operation even under off-center loading conditions, reducing the risk of piston binding or seal damage.
-
Integrated Stop-RingThe built-in stop-ring mechanically limits piston overtravel, preventing cylinder over-extension and protecting both the cylinder and the application structure from potential damage caused by excessive stroke.
-
Ultra-Low Profile HeightThe extremely low closed height allows the cylinder to be used in tight spaces, making it ideal for lifting, spreading, or clamping operations where vertical clearance is severely limited.
-
Ready-to-Use Hose AssemblyAll models are supplied with an 18 cm hydraulic hose terminated with a CEJN female coupler, making connection and operation easier in narrow, confined spaces.
-
Advanced Surface Treatment – Gas Nitriding + Post-OxidationThe cylinder undergoes gas nitriding followed by a post-oxidation process, creating a hardened, corrosion-resistant surface. This treatment significantly enhances protection against rust, pitting, and wear, while also improving resistance to eccentric loading stresses.
