ZBD 2512 Differential Cylinder Data sheet 07./DS
Description: The STORZ hydraulic cylinder series ZBD 2512 for the nominal pressure of 250 bar is replaceable with the CDH1 series. By fixing the mounting dimensions, installation length, area ratios, piston rod ends and connection thread an international exchangeability with the CDH1 series is guaranteed. There are the same mounting dimensions for cylinders with and without cushioning. As standard two rod diameters are allocated to each piston diameter. As standard 6 different mountings and 6 sealing variations are available. The position of the pipe connection, as well as ventilation, startup valve and throttle screw can be freely selected. Standard (order as mentioned) 1,2,3,4. Attachments must be ordered separately.
