Extended Fatigue Life
High-strength alloy steel body and forgings, special heat treatment and ultrasonic-tested welds withstand high-pressure alternating loads; fatigue rating exceeds 2 million cycles.
Low-Friction Start-Up
Precision chrome-plated piston rod with surface hardness HV900–1100 and roughness Ra<0.1μm, combined with low-friction seals, ensures very low breakaway pressure and stick-slip free operation.
Versatile Anti-Corrosion
Available surface finishes include hard chrome, nickel/chromium plating, ceramic thermal spray, laser cladding, and QPQ nitriding to resist harsh conditions such as coastal salt spray, mining dust, and wet environments.
Integrated Cushioning
Built-in adjustable end-of-stroke cushions absorb swing impact, reducing machine vibration and protecting linkage components while maintaining digging power and response.
Smart Sensing Options
Ready for integration of magnetostrictive displacement sensors or LVDT for closed-loop position control with ±0.1mm accuracy, supporting electrification upgrades.
Modular Hydraulic Accessories
Easily combined with counterbalance valves, hydraulic locks, proportional throttles, and pre-assembled hoses/tubing to reduce customer assembly time.
Maintenance-Free Pivot
Rod end and base end forgings feature standard self-lubricating composite bushings, grease-free, wear-resistant, and long service life; optional spherical bearings or hydrostatic bushings available.
