About the Airtac SAID200 Double Rod Cylinder SAID200BX700S
The AirTAC SAID200X700-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200mm bore and 700mm stroke. Because the piston rod exits both end covers, the annulus area is identical on extend and retract. This means you get exactly 15079 N of force in both directions at 0.5 MPa, eliminating speed and force asymmetry. The -S suffix indicates a built-in magnet for position sensing.
This unit is configured with SUS304 stainless steel rods (code B) for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel features sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches along either rod extension. As a true profile cylinder, it is dimensionally interchangeable per ISO 15552.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX700S Is Used
Heavy-Duty Transfer Carriages
Drives large material transfer carts with equal push and pull force, using the twin rods to prevent rotational twisting under heavy off-center loads.
Symmetric Force Actuation
Ideal for presses and molding ejection where the 15079 N clamping force must precisely match the retraction force, ensuring consistent cycle timing.
Dual-Side Tooling Stations
Mounts the primary workpiece on the front rod and a secondary cam or limit flag on the rear rod to trigger downstream operations without extra sensors.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX700S the Right Cylinder?
Select this 200mm bore model when an application requires massive bidirectional force (15079 N at 0.5 MPa) and strict anti-rotation control. Stepping down to a 160mm bore yields 9425 N, while staying at 200mm guarantees high stability for heavy transfer carriages. The twin-rod design is chosen over a single-rod SAI when you need to mount a cam or position flag on the rear rod, or drive a secondary mechanism synchronously.
At 700mm stroke, the long unsupported rod length makes the cylinder susceptible to rod-bearing bending under side loads; always use an external guide rail to prevent premature wear. Remember that a plain SAID does not hold its load when air is exhausted—the piston drifts without live pressure. For position holding, consider a SAIL lock, BSAID clamp-lock, or an external rod lock. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB/CA/CB/CR).

- ✓ 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 SAID200BX700S FAQ
Because the double-rod design subtracts the rod area on both sides, the push and pull forces are identical. It delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa in both directions.
Yes, the SAID200X700-S is dimensionally interchangeable per ISO 15552. It shares the exact mounting interface and footprint of other ISO 15552 double-rod profile cylinders, making it a drop-in replacement.
