About the Airtac SAID200 Double Rod Cylinder SAID200BX900S
The AirTAC SAID200X900-S 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, yielding identical extend and retract forces. This design generates 15079 N of thrust each way at 0.5 MPa, scaling to 27141 N at 0.9 MPa. The extended 900 mm stroke requires careful alignment, but the twin SUS304 stainless steel rods provide superior resistance to deflection compared to a single rod.
Because the rod occupies both sides of the piston, the annulus area is perfectly balanced, ensuring equal speed and force in both directions. This specific configuration includes a magnet for position sensing and uses PT tapered ports sized at G3/4. The extruded aluminum barrel features sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches precisely where needed along the stroke.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX900S Is Used
Symmetric Force Transfer
Drives heavy transfer carriages requiring exactly equal push and pull forces, using the balanced annulus area to maintain consistent velocity in both directions.
Twin-Station Actuation
Mounts a primary workpiece on the front rod and a secondary cam or tool on the rear rod end to operate synchronized mechanisms from a single actuator.
Anti-Rotation Slides
Leverages the dual SUS304 rods to guide heavy vertical lifts and prevent mechanical binding, replacing bulkier external guide rails in heavy machinery.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX900S the Right Cylinder?
Selecting this 200 mm bore model is appropriate when an application demands the maximum standard force profile in the SAID range, as smaller bores like the 160 mm deliver only 9425 N at 0.5 MPa. If your force requirements are lower, stepping down reduces unnecessary physical size and air consumption. The double-rod architecture is chosen over a single-rod SAI when the mechanism requires strict anti-rotation guidance, dual-side work mounting, or a rear-rod position flag. For a drop-in replacement, ensure the target system matches the ISO 15552 mounting interface and uses compatible accessories from the SAID set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
At a 900 mm stroke, the unsupported length of the twin rods introduces a risk of rod-bearing bending under heavy lateral loads; an external guide rail should be used to support the workpiece. Note that a plain SAID cylinder does not hold its position when air pressure is lost—the adjustable air cushions only decelerate the piston near stroke ends. If the load must be prevented from drifting during an air loss event, consider a SAIL locking cylinder or an external pilot-operated check valve.

- ✓ 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 SAID200BX900S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the push and pull forces are identical. It delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa in both directions.
Yes, the SAID200X900-S is dimensionally interchangeable per ISO 15552 profile cylinder standards. It uses the same mounting interface and accessories (Basic, FA, LB, TC, FTC, TCM1, TCM2) as other ISO 15552 double-rod cylinders, making it a drop-in replacement.
