About the Airtac SAID200 Double Rod Cylinder SAID200BX70
The AirTAC SAID200X70 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 70 mm stroke. Because the twin SUS304 stainless steel rods occupy both sides of the piston, the annulus area is identical in each direction, yielding an equal extend and retract thrust of 15079 N at 0.5 MPa. This symmetric force is ideal for mechanisms requiring balanced push-pull dynamics.
A rod extends from both end covers, allowing you to mount the primary workpiece on one end and a position flag or secondary cam on the rear rod. The extruded aluminum barrel includes sensor grooves on both sides, though this unit lacks the -S magnet and requires external limit detection.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX70 Is Used
Symmetric Force Pressing
Delivers 15079 N of balanced thrust in both directions for heavy-duty pressing and forming operations that require consistent push and pull forces.
Twin-Station Actuation
The through-rod design allows one end to drive a primary workpiece while the opposite rear rod end simultaneously actuates a secondary mechanism or conveyor gate.
Anti-Rotation Slides
Dual 40 mm SUS304 rods provide high torsional resistance, keeping heavy loads guided and preventing rotation during vertical lifting and transfer tasks.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX70 the Right Cylinder?
Choose this 200 mm bore when an application demands massive symmetric force, as stepping down to a 160 mm bore yields only 9425 N at 0.5 MPa. The double-rod design is selected over a single-rod SAI when twin-side guidance and anti-rotation stability are critical. With a 70 mm stroke, side-load bending on the 40 mm rods is minimal.
This cylinder is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 double-rod cylinders. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and features PT tapered G3/4 ports. Note that this plain cylinder does not hold its load when air is exhausted; use a BSAID clamp-lock or external rod lock for position holding.
Quick checklist
- ✓ 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 SAID200BX70 FAQ
Because the double-rod design creates equal annulus areas on both sides, the cylinder provides 15079 N of force in both extend and retract directions at 0.5 MPa, and 21110 N at 0.7 MPa.
Yes, the SAID200X70 is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 double-rod cylinders, utilizing PT tapered G3/4 ports and a standard mounting interface.
