Nitriding Hydraulic Cylinder

RIVERLAKE’s QPQ Series hydraulic cylinders utilize a specialized Quench-Polish-Quench (QPQ) coating process on all internal and external components. This advanced surface treatment significantly enhances wear resistance, corrosion resistance, and fatigue strength – essential properties for demanding hydraulic applications.By applying the full QPQ treatment (nitrocarburizing, polishing, and re-oxidation) to every part, RIVERLAKE ensures these cylinders deliver exceptional durability and long-term performance across all models.
