             Installation guidelines: 
            Requires intermediate support bracket for strokes >1000mm. Maintain 0.5–1mm alignment tolerance during mounting. 
            Lubricate through air supply (ISO VG32 oil mist) at 1 drop/minute/port.

             Critical note: 
            Not suitable for side load applications exceeding 150N. Use guided cylinder configurations 
            when lateral forces are present. Maximum side load capacity reduces by 40% at full extension.
