Introduction
In a fluid transmission system, power is transmitted and controlled through a pressurized fluid (liquid or gas) in a closed circuit: Normal system
Its components are designed and sold for specific fluid pressure:
Hydraulic cylinders and air cylinders are one of these components, which are devices that convert fluid power into linear mechanical force and motion: It includes a transport
Moving parts, namely the piston and piston rod that move in the cylinder:
Although this standard provides codes and dimensioning methods for cylinder installation, it does not cover all dimensions: Code specified in this standard
For the future formulation of interchangeability standards is not perfect, it only establishes a unified and standardized description of installation dimensions:
Without causing confusion or misunderstanding, the code specified in this standard can also be used for the size of similar products:
Fluid transmission system and components
Cylinder installation size and installation type code
1 Scope
This standard specifies the installation dimensions and identification codes of the installation type of hydraulic cylinders and air cylinders (hereinafter referred to as cylinders), including: installation dimensions of cylinders
Dimensions, external dimensions, accessory dimensions and connection port dimensions, as well as the identification code of the installation type and accessory type:
This standard does not include all hydraulic cylinders and cylinder installation types and accessory types:

4 Identification code of piston rod end type
4:1 Reference point and code
4:1:1 Overview
4:1:1:1 First reference point
The axial size of the cylinder is determined by the reference point, which is the same for all cylinders no matter how the cylinder is installed: The theoretical basis
The Punctual Point (TRP) is the transfer point where the force is transferred from the piston rod to the moving parts, called the first reference point:
4:1:1:2 Second reference point
For a double-piston rod cylinder, the second reference point refers to the point from the first reference point to the shoulder of the other end of the piston rod as ZM: The reference point is
The reference point used to install the piston rod attachment at the other end:
4:1:2 Flat piston rod end
For the flat piston rod end, the reference point is the intersection point of the piston rod end surface and the piston rod axis, as shown in Figure 1:
