 Installation requirements: 
            Maintain 0.5mm minimum clearance between rod end and load during alignment. 
            For vertical mounting, use auxiliary guide mechanisms when payload exceeds 50kg. 
            Lubricate through air port using 1-2 drops of ISO VG32 oil every 8 hours of continuous operation.
