They allow the piston rod to lock in any position. Piston rod clamping is mechanically obtained by springs actuated purpose-made jaws. This method allows to lock the cylinder in the desired position, should the air pressure drop. The piston rod lock device is not a safety device. Operational characteristics Construction characteristics "Attention: Dry air must be used for application below 0°C" Mounting bracket Body Clamping jaws Piston Seal Springs Anodised aluminium Anodised aluminium Hardened alloy copper Acetal resin NBR Springs steel Use and maintenance Operate within the specified technical characteristics. The piston rod lock does not require maintenance if properly utilised. The working inlet port has to be pressurised for assembling the piston rod lock device on cylinder. Alternatively adjust the jaws with screw located on connection. Spare parts are not available.
