About the Airtac SAID200 Double Rod Cylinder SAID200BX260
The AirTAC SAID200X260 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical motion. Because a stainless steel rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 15079 N of force each way at 0.5 MPa. This equal-force characteristic eliminates speed discrepancies between strokes, ensuring highly stable dynamics for massive payloads.
Equipped with SUS304 stainless steel rods (option B), this 200 mm bore unit provides superior corrosion resistance for harsh or washdown environments. The extruded aluminum barrel features sensor grooves on both sides for flexible CMSE or DMSE switch mounting. You can drive a primary workpiece from the front rod while using the rear protrusion to mount a cam, position flag, or secondary mechanism, maximizing anti-rotation stability.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX260 Is Used
Symmetric Pressing
Applies 15079 N of equal force in both directions for heavy-duty pressing and forming operations where retract power must match extend power.
Twin-Station Transfer
Drives two synchronized workstations simultaneously from a single piston, utilizing both rod ends to move parallel assemblies at identical speeds.
Anti-Rotation Guidance
Leverages the dual-rod structure to guide heavy vertical loads without twisting, replacing complex external linear guides in compact machinery.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX260 the Right Cylinder?
Select this 200 mm bore model when an application demands immense bidirectional force that a smaller bore cannot provide, such as stepping up from a 160 mm bore (9425 N at 0.5 MPa). The twin-rod architecture is specifically chosen over a single-rod SAI when the load requires dual-side guidance to prevent rotation, or when a rear rod is needed for external limit sensing. Note that a plain SAID does not hold its position if air pressure is lost; for dead-load holding, consider an external pilot-operated check valve or the BSAID clamp-lock variant.
To replace an existing ISO 15552 cylinder, match the 200 mm bore, 260 mm stroke, and G3/4 PT ports. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 260 mm stroke is relatively short for this massive bore, side-load bending stress on the rod bearing is minimal, though external guidance is always recommended for heavy loads. As a double-rod design, ensure you have adequate rear clearance for the through-rod.
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 SAID200BX260 FAQ
Because it is a double-rod cylinder, the effective piston area is identical in both directions. It delivers 15079 N of force both extending and retracting at 0.5 MPa, and 21110 N at 0.7 MPa.
Yes, the SAID200X260 is dimensionally interchangeable with other ISO 15552 profile cylinders. Ensure you match the G3/4 port threads, mounting accessories (Basic, FA, LB, TC, FTC, TCM1, TCM2), and account for the extra rear clearance required for the double-rod.
