About the Airtac SAID200 Double Rod Cylinder SAID200BX170S
The AirTAC SAID200X170-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical actuation. Because a stainless SUS304 rod exits both end covers, the effective piston area is identical in each direction, yielding an equal extend and retract force of 15079 N at 0.5 MPa. The integrated -S magnet pairs directly with CMSE reed and DMSE solid-state sensors riding in the dual-side barrel grooves.
This through-rod layout allows engineers to mount a primary workpiece on the front end and a secondary cam, position flag, or guidance mechanism on the rear. Operating at 30-500 mm/s, it features adjustable air cushions at both ends to decelerate the massive 200 mm bore payload smoothly near stroke extremes.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX170S Is Used
Symmetric Press Transfer
Drives heavy press feeders with equal push and pull power, using the rear rod end to mount a synchronized cam for timing the material grip.
Anti-Rotation Lift
Elevates large machining fixtures without rotational drift, leveraging the twin through-rod guidance to keep the heavy load perfectly stable.
Dual-Side Tooling Actuation
Operates two forming tools simultaneously from opposite ends of the cylinder, ensuring perfectly matched timing and identical clamping force.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX170S the Right Cylinder?
Selecting this 200 mm bore is ideal when an application demands immense bidirectional force that a smaller neighbour, like the 160 mm bore delivering 9425 N at 0.5 MPa, cannot supply. The double-rod architecture is specifically chosen over a single-rod SAI when the mechanism requires superior anti-rotation guidance, twin-station actuation, or rear-side position sensing. Configuration requires a 170 mm stroke, G3/4 PT ports, and a compatible mounting accessory from the SAID subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
Note that the variable air cushion only decelerates the piston near stroke end; it does not lock or hold the load. If the machinery must maintain position upon loss of air pressure, specify a BSAID clamp-lock cylinder or an external pilot-operated check valve. Although the 170 mm stroke is below the 300 mm side-load threshold, the heavy rod mass still benefits from external guide rails to prevent rod-bearing bending.

- ✓ 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 SAID200BX170S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the extend and retract forces are equal. It delivers 15079 N both ways at 0.5 MPa, and 21110 N both ways at 0.7 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 double-rod profile cylinders, matching the 200 mm bore, 170 mm stroke, and G3/4 port interface.
