This document specifies the mounting dimensions required for interchangeability of rod-end spherical
eyes of pneumatic cylinders. The rod-end spherical eyes have been designed specifically for use with
1 000 kPa [10 bar1)] series cylinders manufactured in accordance with ISO 6432 and ISO 15552, but this
does not limit their application.
The spherical bearing end eyes are used on piston rods of pneumatic 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 pressure according to ISO 6432, ISO 15552 and ISO 21287.
