 Installation recommendation: 
            Use M12x1.75 mounting bolts (grade 8.8 or higher) with anti-vibration washers. 
            Lubricate through integrated grease nipple (NLGI #2 lithium soap base) every 
            500km of stroke operation. Maintain 0.5-1mm alignment tolerance during mounting.
