About the Airtac SAID200 Double Rod Cylinder SAID200BX65S
The AirTAC SAID200X65-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 65 mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 15079 N of force in either direction at 0.5 MPa. This through-rod design is ideal for driving dual mechanisms or mounting a rear-position flag.
Equipped with a piston magnet (-S), this variant directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors seated in the dual-side barrel grooves. It uses SUS304 stainless steel rods for superior corrosion resistance and features PT tapered port threads (G3/4) for reliable pneumatic sealing.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX65S Is Used
Symmetric Press Drive
Provides perfectly balanced push and pull forces for heavy presses, ensuring consistent actuation speed regardless of the direction of travel.
Twin-Station Transfer
Simultaneously drives two linked workstations from a single piston, using both protruding rod ends to synchronize opposing operations.
Anti-Rotation Heavy Slide
Leverages the dual-rod geometry to guide heavy loads without twisting, eliminating the need for external linear bearings in rigid assemblies.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX65S the Right Cylinder?
Select this 200 mm bore when your application demands immense bidirectional power, as it generates 15079 N equally in both directions. If a smaller footprint suffices, step down to the 160 mm bore which provides 9425 N both ways at 0.5 MPa. Choose the SAID twin-rod architecture over a single-rod SAI when you need intrinsic anti-rotation guidance, dual-side work mounting, or rear-rod cam actuation.
This cylinder does not hold its load when air pressure is lost; if your process requires static position holding, consider the SAIL lock or BSAID clamp-lock series instead. As a dimensionally interchangeable ISO 15552 unit, it serves as a drop-in replacement for other ISO 15552 double-rod cylinders. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. At a 65 mm stroke, side-load bending is minimal, though long unsupported strokes should always use an external guide.

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 SAID200BX65S FAQ
Because the rod occupies both sides of the piston, the effective area is equal in both directions. It delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa for both extend and retract strokes.
Yes, it is dimensionally interchangeable per ISO 15552 and can serve as a drop-in replacement for other ISO 15552 double-rod cylinders. The included magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors.
