This International Standard establishes the mounting dimensions required for interchangeability of rod end spherical eyes of hydraulic cylinders. These rod end spherical eyes have been designed specifically for use with cylinders manufactured in accordance with ISO 6020/1 and ISO 6022, but this does not limit their application.
The spherical bearing end eyes are used on piston rods of hydraulic cylinders for mechanically transmitting the cylinder force under oscillatory rotational and tilting movements. The design of the rod end spherical eyes is based on the maximum forces resulting from the specified internal diameter of the cylinders and pressures according to ISO 3320 and ISO 3322.
