About the Airtac SAID200 Double Rod Cylinder SAID200BX280
The AirTAC SAID200X280 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 200 mm bore and 280 mm stroke. Because the piston rod exits both end covers, the effective annulus area is identical on extend and retract, yielding an equal 15079 N of force in both directions at 0.5 MPa. This symmetric thrust is ideal for mechanisms requiring identical push and pull dynamics.
This specific configuration features SUS304 stainless steel rods (material code B) for superior corrosion resistance in harsh environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. A rear rod protrudes from the back head, which allows engineers to mount a secondary cam, position flag, or external guide to prevent rotation.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX280 Is Used
Symmetric Force Pressing
Delivers identical 15079 N thrust on extend and retract for precision pressing and forming tasks where push and pull forces must match exactly.
Twin-Station Actuation
Drives two linked stations simultaneously using the front and rear rod ends, ensuring perfectly synchronized motion without external linkages.
Anti-Rotation Slides
The dual through-rods keep heavy loads guided and prevent rotational twist during vertical lifting and heavy-duty transfer operations.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX280 the Right Cylinder?
Select this 200 mm bore model when an application demands massive symmetric force, as it provides 15079 N each way at 0.5 MPa. If your mechanism requires less thrust, stepping down to a 160 mm bore yields 9425 N both ways while saving space. Conversely, if you need to hold a load statically without live air pressure, note that this standard SAID cylinder will drift when air is lost; you should instead evaluate an AirTAC SAIL (pneumatic lock) or BSAID (clamp-lock) cylinder.
This SAID200X280 variant uses PT tapered port threads and lacks a magnet (-S not specified), so it cannot host CMSE reed or DMSE electronic sensors without modification. It is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 double-rod cylinders. Because the stroke is 280 mm, the extended rod length increases side-load stress on the rod bearing; for such long strokes, always use an external guide rail to prevent bending and premature seal wear.

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 SAID200BX280 FAQ
Because the rod occupies both sides of the piston, the SAID200X200 provides equal force in both directions. It delivers 15079 N at 0.5 MPa, 21110 N at 0.7 MPa, and 27141 N at 0.9 MPa.
The double-rod design allows a cam or sensor flag to be mounted on the rear rod while providing equal push/pull force and better anti-rotation guidance. Its ISO 15552 mounting interface makes it a drop-in replacement for other standard profile cylinders.
