 Installation guidelines: 
            Use M10 grade mounting bolts with anti-vibration washers. Lubricate rod end bearings 
            with ISO VG32 hydraulic oil before initial operation. Maintain 0.5mm minimum clearance 
            between cylinder body and machine frame for thermal expansion.
