About the Airtac SAID200 Double Rod Cylinder SAID200BX250
The AirTAC SAID200X250 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetric actuation. Because the piston rod extends from both end covers, the annulus area is identical on both sides, yielding exactly 15079 N of force in both extend and retract directions at 0.5 MPa. This through-rod architecture provides superior anti-rotation guidance and allows a secondary mechanism or position flag to be driven from the rear.
This specific configuration features a SUS304 stainless steel rod (material code B) for superior corrosion resistance in harsh environments. It utilizes PT tapered port threads and lacks a piston magnet. The extruded aluminum barrel includes dual-side sensor grooves, though electronic tracking requires external limit switches given the absence of the -S magnet option.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX250 Is Used
Symmetric Press Drive
Drives a heavy forming press where the rear rod simultaneously operates a mechanical knockout arm, utilizing the equal 15079 N bidirectional force.
Twin-Station Transfer
Actuates two parallel workholding stations from a single piston, ensuring perfectly synchronized movement and preventing torsional load twist.
Anti-Rotation Heavy Slide
Guides a massive industrial welding fixture with high side-load resistance, leveraging the double-rod geometry to prevent platform rotation.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX250 the Right Cylinder?
Selecting the SAID200X250 is ideal when a massive, perfectly balanced force profile is required without the asymmetry of a single-rod SAI cylinder. If an application needs slightly less force, stepping down to the 160mm bore provides 9425 N at 0.5 MPa, but this 200mm variant is necessary when moving extreme payloads up to 15079 N per direction. Because the stroke is 250mm, the long unsupported rod span requires an external guide to prevent rod-bearing bending under heavy side loads.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders, utilizing a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that the adjustable air cushions only decelerate the piston near stroke end; this plain cylinder will drift if air pressure is lost, so a SAIL or BSAID lock variant is required for fail-safe load 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 SAID200BX250 FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It delivers 15079 N of force in both extend and retract directions at 0.5 MPa, and 21110 N at 0.7 MPa.
Yes, the SAID200X250 is dimensionally interchangeable per ISO 15552 profile standards. It uses standard mounting dimensions and PT tapered ports, though you must ensure your mounting accessory is from the SAID-compatible set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
