Airtac SAID200 Double Rod Cylinder SAID200AX110
The AirTAC Airtac SAID200 Double Rod Cylinder SAID200AX110 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 110mm stroke, G3/4 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 SAID200 Double Rod Cylinder SAID200AX110
The AirTAC SAID200X110 is a double-acting, double-rod profile cylinder built to ISO 15552 mounting dimensions. A single piston drives a rod out of both end covers, yielding perfectly symmetric dynamics. Because the rod occupies both sides of the piston, the annulus area is identical in each direction, giving an equal extend and retract thrust of 15079 N at 0.5 MPa (up to 27141 N at 0.9 MPa). The unit omits a magnetic piston, so it is not compatible with CMSE or DMSE position switches.
This model features a 40 mm SUS420J2 stainless steel rod (material code A) for high corrosion resistance and carries a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for future retrofit flexibility. Its adjustable air cushions at both ends decelerate the 30-500 mm/s motion smoothly, though the cushion only slows the piston and does not hold the load if air pressure drops.

Where the Airtac SAID200 Double Rod Cylinder SAID200AX110 Is Used
Anti-Rotation Slides
The through-rod design provides dual-side guidance to keep heavy workpieces from twisting during high-force machining or clamping operations.
Symmetric-Force Transfer
Delivers identical 15079 N thrust on extend and retract at 0.5 MPa, ensuring perfectly balanced motion for heavy press and transfer duties.
Twin-Station Actuation
Mount the primary tool on the front rod end and a secondary cam or limit flag on the rear rod to operate a secondary mechanism simultaneously.
Is the Airtac SAID200 Double Rod Cylinder SAID200AX110 the Right Cylinder?
Choose this 200 mm bore when an application requires massive symmetric force, as it generates 15079 N each way at 0.5 MPa. If your layout can tolerate slightly lower thrust, stepping down to a 160 mm bore yields 9425 N both ways while saving footprint. The twin-rod layout is selected over a single-rod SAI when the mechanism needs dual-side guidance to prevent rotation, or when a rear cam and position flag must drive a secondary mechanism. Note that a plain SAID will drift if air is lost; if the load must be held without live pressure, consider an external rod lock or the BSAID clamp-lock variant.
For installation, specify the 110 mm stroke, 200 mm bore, and PT port thread. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR accessories used on single-rod SAI units. Because the rear rod protrudes from the back cover, ensure you leave adequate clearance behind the cylinder. Although the 110 mm stroke is relatively short, the heavy 40 mm twin rods still impose significant side-load leverage on the rod bearing if the workpiece is offset, so utilize an external guide for rigidly mounted loads.

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 SAID200AX110 FAQ
Because the 40 mm rod occupies both sides of the piston, the effective area is identical in both directions. It generates 15079 N of thrust at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa on both extend and retract strokes.
Yes, the SAID200X200 is dimensionally interchangeable per ISO 15552 and can serve as a drop-in replacement for other ISO 15552 double-rod profile cylinders. It uses the standard mounting interface and accepts Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories.
