About the Airtac SAID200 Double Rod Cylinder SAID200BX650
The AirTAC SAID200X650 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 650 mm stroke. Because a rod exits both ends, the annulus area is identical on each side, yielding exactly 15079 N of force in both extend and retract directions at 0.5 MPa. This through-rod geometry provides superior anti-rotation guidance for heavy loads compared to a single-rod unit.
This configuration uses a SUS304 stainless steel rod for corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible CMSE or DMSE switch mounting. Note that the rear rod protrudes beyond the back cover, requiring additional clearance in your machine layout.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX650 Is Used
Heavy-Duty Pressing
Delivers 15079 N of equal extend and retract force for symmetric pressing and forming operations without stroke direction force loss.
Twin-Station Transfer
Uses both rod ends to drive two parallel mechanisms simultaneously, ensuring perfectly synchronized motion across stations.
Anti-Rotation Slides
The dual-rod architecture prevents piston rotation, guiding heavy industrial slides and lifting platforms without external torsion.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX650 the Right Cylinder?
Select this 200 mm bore model when an application demands massive bidirectional force and high torsional rigidity. If you need less force, stepping down to the 160 mm bore yields 9425 N both ways at 0.5 MPa. Choose this double-rod SAID over a single-rod SAI when you need to mount a secondary cam, position flag, or tool on the rear rod extension. It supports mounting accessories Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Since this cylinder lacks a magnet, it cannot host internal sensors. At 650 mm stroke, the long unsupported rod is prone to bending under heavy side loads; integrate an external linear guide to prevent rod-bearing damage. This cylinder drifts when air is lost—use an external rod lock or SAIL/BSAID cylinder if position holding is required.
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 SAID200BX650 FAQ
It provides 15079 N of force in both the extend and retract directions at 0.5 MPa, and 21110 N at 0.7 MPa, because the double-rod design equalizes the piston area on both sides.
Yes, the SAID200X650 is dimensionally interchangeable per ISO 15552 profile standards, making it a drop-in replacement for other ISO 15552 double-rod cylinders with a 200 mm bore and 650 mm stroke.
