ISO 6099:2009 pdf download – Fluid power systems and components – Cylinders – Identification code for mounting dimensions and mounting types
1 Scope
This International Standard establishes a convention for the identification of mounting dimensions and types used in the mounting of fluid power cylinders. It specifies a code for identifying cylinder mounting, envelope, accessory and connector dimensions, and for cylinder mounting and accessory types. This International Standard does not represent a standard list of all fluid power cylinder mounting and accessory types.

4 Identification code for rod end types
4.1 Reference points and letter codes
4.1.1 General
4.1.1.1 First point of reference
Axial dimensions are determined from a reference point that is the same for all cylinders, whatever their 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.
4.1.1.2 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.
4.1.2 Plain rod end
For a plain rod end, the reference point is located on the rod centreline at the end of the piston rod. See Figure 1 .
