11、25 MPa (250 bar) series Introduction In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. One component of such systems is the fluid power cylinder. This is a device that converts power into linear mechanical force and moti
12、on. It consists of a movable element, i.e. a piston and piston rod, operating within a cylindrical bore. DIN ISO 6022:2008-06 51 Scope This International Standard establishes mounting dimensions for hydraulic cylinders for use at 25 MPa 250 bar1), as required for interchangeability of these cylinder
13、s. NOTE This International Standard allows manufacturers of hydraulic equipment flexibility in the design of 25 MPa (250 bar) cylinders and does not restrict technical development; however, it does provide basic guidelines. 2 Normative references The following referenced documents are indispensable

40、the piston rod cavity of the cylinder can be two or more times the working pressure of the hydraulic system. In these cases, flange ports in accordance withISO 6162-1 or ISO 6164, as shown in this table, may not have sufficient pressure ratings. When flange ports with a higher pressure rating are ne
41、eded, they can be selected from the higher pressure series in ISO 6162-2 and ISO 6164.
