About the Airtac SAID200 Double Rod Cylinder SAID200BX180
The AirTAC SAID200X180 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical motion. A single piston drives a rod out of both end covers, meaning the annulus area is identical on extend and retract. Consequently, it generates exactly 15079 N of thrust and pull force at 0.5 MPa in either direction. The standard 180 mm stroke operates efficiently within the 30-500 mm/s speed range for this large 200 mm bore.
This unit features a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. PT tapered G3/4 port threads ensure a rigid, leak-free pneumatic connection. Because the rear rod protrudes through the back cover, you can mount a position flag or secondary cam there while utilizing the shared extruded aluminum barrel with sensor grooves on both sides. Note that the overall length requires extra rear clearance compared to a single-rod SAI.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX180 Is Used
Symmetric Pressing
Utilizes the equal 15079 N force in both directions to execute high-tonnage pressing and forming operations without asymmetric speed drift.
Twin-Station Transfer
Drives two separate mechanisms simultaneously by mounting tooling on the front rod end and a secondary cam or linkage on the rear rod end.
Anti-Rotation Guidance
Leverages the dual through-rod design to keep heavy 200 mm bore loads perfectly guided and resistant to torsional deflection during transit.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX180 the Right Cylinder?
Select this 200 mm bore when an application demands massive equal-force transfer both ways, as stepping down to a 160 mm bore drops the output to 9425 N at 0.5 MPa. The twin-rod architecture is chosen over a single-rod SAI when you need strict anti-rotation guidance, dual-side workpiece mounting, or rear-cam actuation. Since the stroke is 180 mm, the 40 mm rod and M36x2 thread handle substantial loads, but always verify side-load limits.
A plain SAID does not hold its load if air pressure drops or the valve centers; the piston will drift. For dead-end holding without live pressure, consider an external pilot-operated check valve or switch to a BSAID clamp-lock variant. This model is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 double-rod cylinders. Specify the PT G3/4 port, appropriate mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2), and note no magnet is installed.

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 SAID200BX180 FAQ
Because the rod exits both ends, the effective piston area is identical on extend and retract. It delivers 15079 N of force in both directions at 0.5 MPa, and 21110 N at 0.7 MPa.
Yes, the SAID200X200 is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 double-rod profile cylinders, utilizing a PT G3/4 port and a 40 mm SUS304 rod.
