Airtac SAID50 Double Rod Cylinder SAID50X15
The AirTAC Airtac SAID50 Double Rod Cylinder SAID50X15 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 15mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAID50 Double Rod Cylinder SAID50X15
The AirTAC SAID50X15 is a double-acting, double-rod profile cylinder operating on the ISO 15552 mounting interface. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding a perfectly symmetric 825 N of force each way at 0.5 MPa. This through-rod architecture provides superior anti-rotation stability compared to a single-rod SAI.
The 15 mm stroke is a non-standard, made-to-order dimension, enabling highly compact short-throw work. It features adjustable air cushioning at both ends and dual sensor grooves on the extruded aluminum barrel. Without a magnet specified, it is configured for mechanical actuation rather than electronic position sensing.

Where the Airtac SAID50 Double Rod Cylinder SAID50X15 Is Used
Compact Symmetric Clamping
Ideal for short-throw clamping where equal extend and retract forces ensure consistent grip pressure on both strokes within a tight 15 mm travel.
Twin-Station Actuation
Drive two separate mechanisms simultaneously from one piston, using the front rod for the primary work and the rear rod for a secondary motion.
Anti-Rotation Slides
The dual-rod geometry prevents piston rotation during the brief 15 mm travel, providing precise linear guidance for delicate assembly tooling.
Is the Airtac SAID50 Double Rod Cylinder SAID50X15 the Right Cylinder?
Select this twin-rod cylinder when a compact 15 mm stroke requires equal push and pull forces, such as clamping or short indexing. If your application needs slightly less force, stepping down to a bore 40 yields 528 N both ways; stepping up to a bore 63 provides 1402 N. The PT tapered port thread matches the G1/4 standard for this bore size.
A plain SAID does not hold its load when air pressure is lost or exhausted—the piston will drift. For position holding without live pressure, consider an external pilot-operated check valve or the SAIL air-released lock variant. Mounting options are restricted to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets found on single-rod versions.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID50 Double Rod Cylinder SAID50X15 FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. It provides an equal 825 N of force in both extend and retract directions at 0.5 MPa (1154 N at 0.7 MPa).
Yes, the SAID50X15 is dimensionally interchangeable per ISO 15552 and uses the standard PT G1/4 port. It serves as a direct drop-in replacement for other ISO 15552 double-rod profile cylinders.
