Festo Air Cylinder ADNGF-50-25-P-A 554262

The Festo ADNGF-50-25-P-A (Part Number: 554262) is a compact, double-acting pneumatic cylinder designed for use in space-constrained automation applications that require a non-rotating piston rod.¹

It is part of the ADNGF (Compact guided cylinder) series, which features anti-rotation and high load capacity via an integrated guide rod and yoke plate.²

Features and Benefits

Non-Rotating Piston Rod: The integrated guide rod and yoke plate prevent the piston rod from twisting, which is essential for applications requiring precise alignment or tool mounting.³
Space-Saving Design: Its compact profile, conforming to ISO 21287, makes it ideal for use in limited installation spaces.⁴
Elastic Cushioning (“P”): The non-adjustable, flexible polymer cushioning at both ends reduces noise and wear, suitable for small loads and lower speeds.⁵
Sensor Ready: The cylinder is equipped with a magnetic piston for reliable, non-contact end-position sensing using external Festo proximity switches (e.g., SMT/SME series)
