4 Identification code for rod end types
4.1 Reference points and letter codes
4.1.1 General First point of reference
Axial dimensions are determined from a reference point that is the same for all cylinders, whatever thew mounting method. This theoretical reference point (TRP) is the point of force transfer from the piston rod to the movable element This point of reference (TRP) is named the first TRP, Second point of reference
For double rod cylinders, the second TRP is defined by the letter code ZM directly attached to the first point of TRP (see Figure 8). This second TRP is used for accessories on the second rod side.
