The "BA" series pneumatic cylinders for bores from 32 to 63 mm have been designed to extend the range of round profile cylinders according to ISO 6432. The ISO 6432 standard defines the main dimensions of cylinders only for bores from 8 to 25 mm; however, the practicality of using such actuators has necessitated an expansion up to a bore of 63 mm, increasing their usability. The design principles followed in the creation of these actuators prioritized reliability, robustness, and ease of maintenance. In fact, the heads are screwed onto the tube to allow easy inspection, while the pistons are equipped with elastic shock absorbers to better absorb end-of-stroke impacts, providing quiet operation and extending the machine's lifespan.
