A hydraulic actuator that converts pressure energy into mechanical energy to achieve linear motion. The moving components include pistons, piston rods, etc. GB/T 38205 aims to determine the installation dimensions of the 16MPa series single-rod cylinders and is intended to consist of three parts. --- Part 1.Medium series. The purpose is to determine the installation dimensions of 16MPa series medium single-rod cylinders. --- Part 2.Compact series with cylinder diameters of 25 mm to 220 mm. The purpose is to determine the 16 MPa series of compact single-rod cylinders (cylinders The installation dimensions are 25mm~220mm in diameter. --- Part 3.Compact series with cylinder diameters of 250 mm to 500 mm. The purpose is to determine the 16 MPa series of compact single-rod cylinders (cylinders The installation dimensions are 250mm~500mm in diameter. Hydraulic transmission 16MPa series single rod cylinder Installation dimensions Part 2.Cylinder diameter 25mm~ 220mm Compact Series1 ScopeThis document specifies the installation dimensions of the 16MPa series compact hydraulic single-rod cylinders to meet interchangeability requirements. This document is applicable to square head hydraulic single-rod cylinders (hereinafter referred to as hydraulic cylinders) with a nominal pressure of 16MPa and a cylinder diameter of 25mm~220mm. pressure cylinder).
