About the Airtac SAID200 Double Rod Cylinder SAID200BX240
The AirTAC SAID200X240 is a double-acting, double-rod ISO 15552 profile cylinder. A single piston drives a rod out of both end covers, yielding exactly 15079 N of thrust and pull force at 0.5 MPa. Because the annulus area is identical on both sides, extend and retract forces are perfectly equal.
This specific unit uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches wherever needed. The rear rod extension is ideal for mounting a position flag or driving a secondary mechanism.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX240 Is Used
Symmetric Transfer
Drives heavy workpieces with identical push and pull force, ensuring stable dynamics during high-load bidirectional transfers.
Anti-Rotation Slides
The twin rods exiting both ends guide the load against rotation, maintaining precise alignment for heavy machining slides.
Rear-Cam Actuation
Mount a cam or position flag on the rear rod to trigger external limit switches while the front rod performs the primary work.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX240 the Right Cylinder?
Choose this 200 mm bore when you need massive equal-force transfer in both directions, stepping up from a 160 mm bore that provides 9425 N at 0.5 MPa. The twin-rod design is selected over a single-rod SAI when an application requires dual-side guidance, anti-rotation control, or a rear-mounted cam. Note that a plain SAID does not hold its load when air pressure is lost; for dead-drop prevention, consider a BSAID clamp-lock cylinder. This model is dimensionally interchangeable per ISO 15552 and uses the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAID200BX240 FAQ
Because it is a double-rod cylinder, the effective area is the same 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 SAID200X240 is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses a standard PT G3/4 port and supports mounting accessories like FA, LB, and TC.
