About the Airtac SAID200 Double Rod Cylinder SAID200BX650S
The AirTAC SAID200X650-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200mm bore and 650mm stroke. Because a stainless SUS304 rod exits both end covers, the annulus area is identical on each side, yielding equal push and pull forces of 15079 N at 0.5 MPa. The extended rear rod provides a secondary mounting point for a cam or position flag while significantly improving load guidance against rotation.
This through-rod variant includes a magnet (-S) for use with AirTAC CMSE reed and DMSE solid-state sensors, which seat neatly into the extruded aluminum barrel grooves on both sides. Fluid ports are PT tapered threads sized at G3/4. The twin-rod architecture inherently balances internal pressures, ensuring stable velocity during heavy symmetric transfers.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX650S Is Used
Heavy-Duty Pressing
Delivers 15079 N of force in both extend and retract directions for high-tonnage stamping and forming operations.
Symmetric Transfer
Equal annulus area on both sides ensures perfectly balanced speed and force when shuttling massive workpieces between stations.
Anti-Rotation Slides
The twin SUS304 rods prevent piston twist under severe off-center loads, keeping heavy tooling perfectly aligned.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX650S the Right Cylinder?
Selecting this 200mm bore is ideal when massive bidirectional force is required, stepping up from a 160mm bore that yields 9425 N at 0.5 MPa. A double-rod design is chosen over a single-rod SAI when the application demands dual-side guidance, anti-rotation stability, or rear-rod actuation. Note that this cylinder does not hold its load when air pressure is lost; for dead-load holding, consider an AirTAC SAIL or BSAID clamp-lock variant.
At a 650mm stroke, the unsupported rod length is substantial, creating a high risk of rod-bearing bending under side loads. An external guide rail must be integrated to support the workpiece. It is dimensionally interchangeable per ISO 15552, offering a drop-in replacement for other ISO 15552 double-rod cylinders. Mounting options are restricted to 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 SAID200BX650S FAQ
Because the double-rod design subtracts rod area from both sides, it provides equal force in both directions: 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. However, ensure your design accommodates the rear rod protrusion and uses the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
