About the Airtac SAID200 Double Rod Cylinder SAID200BX270S
The AirTAC SAID200X270-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical motion. Because a stainless steel rod exits both ends, the annulus areas match, delivering an equal 15079 N of thrust and pull force at 0.5 MPa in both directions. The -S suffix denotes an integrated magnet for position sensing.
Equipped with SUS304 stainless steel rods and PT tapered ports, this 200 mm bore unit is built for demanding environments. The rear rod extension is ideal for mounting a secondary cam, driving an external mechanism, or mounting a position flag, while providing superior resistance to rotational torque compared to a single-rod SAI.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX270S Is Used
Heavy-Duty Transfer
Moves large fabricated parts between stations with equal push and pull power, utilizing the twin rods to maintain precise alignment under heavy loads.
Dual-Station Actuation
Drives two separate mechanisms simultaneously from a single piston, using both rod ends to operate mirrored clamping or forming tools.
Anti-Rotation Pressing
Applies symmetrical force for pressing bearings or pins, where the double-rod configuration prevents the load from twisting during the stroke.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX270S the Right Cylinder?
Select this 200 mm bore cylinder when an application requires massive bidirectional force that remains perfectly equal, avoiding the speed and force disparities of single-rod designs. If you need less force, stepping down to the 160 mm bore yields 9425 N at 0.5 MPa. For this 270 mm stroke, the 40 mm rod diameter provides substantial rigidity, but the heavy mass dictates external load guidance to prevent rod-bearing bending.
As a true ISO 15552 profile cylinder, it offers drop-in dimensional interchangeability with other standard double-rod cylinders. It uses the SAID mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Note that air cushions only decelerate the piston near stroke end; this cylinder will drift and cannot hold a load without air pressure. For locking needs, consider a BSAID clamp-lock variant or an external pilot-operated check valve.

- ✓ 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 SAID200BX270S FAQ
Because the double-rod design creates equal piston areas on both sides, it provides 15079 N of force in both extend and retract directions at 0.5 MPa, and 21110 N at 0.7 MPa.
Yes, it shares standard ISO 15552 mounting dimensions, making it a drop-in replacement for other double-rod profile cylinders. It uses PT ports and supports AirTAC CMSE reed and DMSE electronic sensors via the built-in magnet.
