 Installation note: 
            Requires minimum 1mm radial clearance for thermal expansion. 
            Lubricate with ISO VG32 hydraulic oil if using non-lubricated air. 
            Maximum side load: 250N at rod end. Always use alignment couplers 
            when connecting to guided mechanisms.
