Surface finish of cylinders and rods directly impacts seal life. Rough surfaces abrade seals, causing premature wear. Recommended rod finish is 0.2–0.4 μm Ra for dynamic seals. Chrome plating or nitriding improves hardness and corrosion resistance. Polishing reduces friction and heat generation. Poor surface preparation is a common cause of seal failure in hydraulic systems, often ove... https://globalsealstech.com/hydraulic-seals/
