8、S-,-,-INTERNATIONAL STANDARD IS0 3321 -1975 (E) Fluid power systems and components - Cylinder bores and piston rod diameters - Inch series 0 INTRODUCTION In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under pressure within an enclosed circuit. One compone

9、nt of such systems is the fluid power cylinder. This is a device which converts power into linear mechanical force and motion. It consists of a movable element, i.e. a piston and piston rod, operating within a cylindrical bore. This International Standard is one of two relating to fluid power cylind

10、er bores and piston rod diameters. The other, relating to a metric series, is IS0 3320, Fluid power systems and components - Cylinder bores and piston rod diameters - Metric series. For future design purposes the metric series is to be preferred to the inch series. 1 SCOPE AND FIELD OF APPLICATION T
