About the Airtac SAID200 Double Rod Cylinder SAID200X125
The AirTAC SAID200X125 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 125 mm stroke. Because a carbon steel rod exits both end covers, the effective piston area is identical on extend and retract. This symmetry yields exactly 15079 N of force in both directions at 0.5 MPa, ensuring perfectly balanced motion for heavy loads.
The through-rod design allows engineers to mount the primary workpiece on one end and a secondary mechanism, position flag, or cam on the opposite end. The extruded aluminum barrel includes sensor grooves on both sides for flexible CMSE or DMSE switch mounting. It uses a G3/4 port and omits the FB, CA, CB, and CR mounts, utilizing a dedicated double-rod accessory set.

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 SAID200X125 Is Used
Anti-Rotation Lifting
Uses the twin through-rods to guide and lift heavy assemblies without the rotational twist common to single-rod actuators.
Symmetric Force Transfer
Pushes and pulls a heavy carriage with identical 15079 N force at 0.5 MPa, ensuring consistent velocity both ways.
Dual-Station Actuation
Drives a primary workpiece on the front rod end while simultaneously moving a secondary mechanism or cam on the rear rod.
Is the Airtac SAID200 Double Rod Cylinder SAID200X125 the Right Cylinder?
Select this 200 mm bore model when an application demands immense thrust matched by equal retraction force, such as lifting or shifting a heavy symmetric load. If you need less force, stepping down to the 160 mm bore yields 9425 N each way at 0.5 MPa. The twin-rod architecture is chosen over a single-rod SAI when superior anti-rotation guidance or rear-side actuation is required.
Remember that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load. If the machinery loses air pressure, the piston will drift. For fail-safe position holding, consider an external rod lock, a pilot-operated check valve, or the BSAID clamp-lock variant. This cylinder is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAID200X125 FAQ
Because the rod occupies both sides of the piston, the push and pull forces are equal. It generates 15079 N in both directions at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes. The SAID200X125 is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses a G3/4 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
