One component of such systems
18、is the cylinder. This is a device that converts fluid power into linear mechanical force and motion. It consists of a moveable element, i.e. a piston and piston rod, operating within a cylindrical bore. ISO 2015 All rights reserved vBS ISO 6020-2:2015BS ISO 6020-2:2015Hydraulic fluid power Mounting
