About the Airtac SAID200 Double Rod Cylinder SAID200AX115
The AirTAC SAID200X115 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 115 mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 15079 N of force each way at 0.5 MPa (up to 27141 N at 0.9 MPa). This symmetric output is ideal for twin-station actuation or driving a secondary mechanism from the rear rod.
This configuration uses a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance, paired with PT tapered port threads and a G3/4 air supply. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Note that the through-rod design makes the overall length longer than a single-rod SAI, requiring extra rear clearance.

Where the Airtac SAID200 Double Rod Cylinder SAID200AX115 Is Used
Symmetric Force Stamping
Delivers 15079 N of equal force in both directions, ensuring consistent stamping and forming pressure on both extend and retract strokes.
Twin-Station Transfer
The through-rod design allows mounting workpieces on both ends, actuating two separate stations simultaneously from one centralized ISO 15552 cylinder.
Anti-Rotation Slides
Dual-rod guidance prevents piston rotation during heavy load transfer, providing precise linear movement for large-scale material handling.
Is the Airtac SAID200 Double Rod Cylinder SAID200AX115 the Right Cylinder?
Choose this 200 mm bore when you need massive bidirectional force that a smaller bore cannot provide, or step down to the 160 mm bore (9425 N at 0.5 MPa) if the load is lighter. A double-rod cylinder is selected over a single-rod SAI when the application demands anti-rotation guidance, dual-side work mounting, or rear-rod position flagging. Ensure your setup matches the ISO 15552 mounting interface using Basic, FA, LB, TC, FTC, TCM1, or TCM2 accessories.
Remember that a plain SAID cylinder does not hold its load when air pressure is lost; it will drift. For fail-safe holding without live pressure, consider an external rod lock, a SAIL air-released lock, or a BSAID clamp-lock cylinder. Because the stroke is 115 mm, side-load bending stresses on the rod bearing are moderate, but external guides are still recommended for heavy off-center loads.

- ✓ 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 SAID200 Double Rod Cylinder SAID200AX115 FAQ
