About the Airtac SAID200 Double Rod Cylinder SAID200BX700
The AirTAC SAID200X700 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 700 mm stroke. Because a SUS304 stainless steel rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 15079 N of force in both directions at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This through-rod design allows you to drive a primary workpiece from the front while attaching a cam, position flag, or secondary mechanism to the rear rod. It utilizes PT tapered port threads and adjustable air cushions at both ends to decelerate the massive 3075 kgf maximum load near stroke endpoints.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX700 Is Used
Heavy-Duty Pressing
Applies 15079 N of precise extend and retract force for symmetric forming and heavy press operations.
Twin-Station Transfer
Drives two synchronized workstations simultaneously using both rod ends for perfectly balanced motion.
Anti-Rotation Slides
Keeps massive loads guided and prevents rotation across the 700 mm stroke without external guides.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX700 the Right Cylinder?
Select this 200 mm bore model when an application requires immense bidirectional force and superior anti-rotation guidance that a single-rod SAI cannot provide. If you need slightly less force, stepping down to the 160 mm bore yields 9425 N both ways at 0.5 MPa. Conversely, if 15079 N is insufficient, there is no larger standard SAID bore.
Because this is a 700 mm stroke, the long unsupported rod is highly susceptible to side-load bending; always use an external guide to prevent rod-bearing damage. Ensure you order with the correct mounting accessories from the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2) as FB, CA, CB, and CR are omitted. Note that this cylinder cannot hold a load if air pressure is lost; for dead-end holding, consider a SAIL or BSAID variant.
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.
