About the Airtac SAID200 Double Rod Cylinder SAID200X250S
The AirTAC SAID200X250-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 250 mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding a perfectly symmetric 15079 N of force in either direction at 0.5 MPa. The integrated -S magnet allows precise end-of-stroke detection using AirTAC CMSE reed or DMSE electronic solid-state switches.
This through-rod architecture is purpose-built for applications requiring high stability and anti-rotation control. You can mount a primary workpiece on one rod end and a secondary cam, position flag, or guiding tool on the opposite end. The extruded aluminum barrel includes sensor grooves on both sides, and adjustable air cushions at both ends absorb heavy impact energies smoothly.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID200 Double Rod Cylinder SAID200X250S Is Used
Heavy-Duty Symmetric Pressing
Utilizes the equal 15079 N extend and retract forces to execute identical pressing and forming operations on both the forward and return strokes.
Twin-Station Actuation
Drives two separate mechanisms simultaneously by mounting a primary tool on the front rod end and a secondary linkage on the rear protruding rod.
Anti-Rotation Transfer Slide
Leverages the dual-rod guidance to move heavy 200 mm bore loads linearly without rotational twist, ensuring precise transfer alignment.
Is the Airtac SAID200 Double Rod Cylinder SAID200X250S the Right Cylinder?
Select this 200 mm bore when your application demands the maximum standard force class in the SAID range, needing 15079 N both ways at 0.5 MPa. If you require less force, step down to the 160 mm bore, which provides 9425 N symmetrically. Choose the SAID double-rod over a single-rod SAI when you need dual-side guidance to prevent rotation, or when a rear rod is required to drive a secondary mechanism. Because the stroke is 250 mm, the relatively long unsupported rod length means you should evaluate side-load conditions and use an external guide to prevent rod-bearing bending.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a PT tapered G3/4 port and supports mounting accessories Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the air cushion only decelerates the piston near stroke end; it does not hold the load. If pressure is lost, the piston will drift. For position holding without live pressure, consider an SAIL lock, BSAID clamp-lock, or an external rod lock.

- ✓ 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 SAID200X250S FAQ
Because the double-rod design occupies area on both sides of the piston, the force is equal in both directions. It provides 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes, the SAID200X250-S is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses the standard mounting interface and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
