Construction Material:
Piston Rod: Crafted from 40Cr steel, heat - treated via hardening and tempering, then hard chrome - plated and mirror - polished. This boosts surface hardness, wear resistance, reduces friction, and ensures smooth, long - lasting operation.
Cylinder Barrel: Made of 25Mn steel, tempered to avoid deformation. It has a higher bearing capacity than common C45 or C20 steel, ensuring durability under high - pressure hydraulic forces.
Barrel/Rod End & Head: Forged from high - strength steel, these parts offer superior strength and toughness to endure operational stress and shock.
Seal Kits: Premium seal kits from renowned brands like NOK or SKF prevent hydraulic fluid leaks, maintain system pressure, and optimize cylinder performance.
