This adjustment avoided a costly redesign and made better use of available space.

Rodless pneumatic cylinders use a sliding piston inside the cylinder body. This design allows for longer stroke lengths while keeping the equipment footprint small. Fewer external moving parts mean higher reliability and efficiency, especially in tight spaces.

Miniaturization plays a key role in these improvements. Compact pneumatic systems work well in environments where floor space is limited but vertical space is available. Although rodless cylinders may cost more at first, they reduce complexity and maintenance costs over time. These benefits make them a smart choice for space-constrained automation.
