The SI40X30H series combines medium-force output (max 502N at 0.8MPa) with space-efficient design, featuring a built-in magnet for position sensing. Its double-acting operation and corrosion-resistant construction make it ideal for repetitive motion tasks. The cylinder achieves over 5,000km service life under standard conditions (clean air, 0.5MPa).
