About the Airtac SAID200 Double Rod Cylinder SAID200BX280S
The AirTAC SAID200X280-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty symmetrical actuation. A single piston drives a SUS304 stainless steel rod out of both end covers, yielding an equal effective area on both sides. This means the cylinder delivers 15079 N of force in both extend and retract directions at 0.5 MPa, eliminating speed and force mismatches between strokes.
Equipped with a magnet for position sensing, this model interfaces directly with AirTAC CMSE reed and DMSE solid-state switches housed in the dual-side sensor grooves. The extruded aluminum barrel features PT tapered ports (G3/4) and adjustable air cushions at both ends. Its through-rod architecture is ideal for mounting a primary workpiece on the front and a cam, position flag, or secondary mechanism on the rear, providing superior anti-rotation guidance for massive loads.

Where the Airtac SAID200 Double Rod Cylinder SAID200BX280S Is Used
Symmetric Force Transfer
Ideal for heavy press or transfer operations requiring identical 15079 N push and pull forces at 0.5 MPa, ensuring consistent cycle dynamics without differential pressure tuning.
Anti-Rotation Slides
The twin 40 mm SUS304 rods exiting both ends provide exceptional torsional rigidity, preventing load rotation on massive material handling gantries.
Dual-Side Tool Actuation
Mount a primary forming tool on the front rod and a secondary cam or position flag on the rear rod to drive two synchronized mechanisms from one cylinder.
Is the Airtac SAID200 Double Rod Cylinder SAID200BX280S the Right Cylinder?
Choose this 200 mm bore when an application demands perfectly balanced 15079 N bi-directional force at 0.5 MPa that a single-rod SAI cannot provide without external compensation. If your load requirement drops, stepping down to a 160 mm bore reduces the both-way force to 9425 N while saving footprint space. The robust 40 mm SUS304 rod and M36x2 thread handle high side loads, but for any stroke at or exceeding 300 mm, an external guide is strongly recommended to prevent rod-bearing bending. This SAID200X280-S is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 double-rod cylinders. It uses the standard SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting single-rod FB, CA, CB, and CR brackets.
Note that the adjustable air cushions only decelerate the piston near stroke end; they do not lock or hold the load. If your setup must maintain position without live air pressure, consider an external pilot-operated check valve, a SAIL locking cylinder, or the BSAID clamp-lock variant. The integrated -S magnet allows precise end-of-stroke verification using CMSE or DMSE sensors.

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 SAID200BX280S FAQ
Because the double-rod design creates equal annulus areas on both sides, it provides 15079 N of force in both extend and retract directions at 0.5 MPa. At 0.7 MPa, it delivers 21110 N both ways.
No, the SAID200X280-S is a standard double-acting cylinder and will drift if air is exhausted or the valve is centered. The adjustable cushions only decelerate the piston at stroke end; for position holding, use a SAIL, BSAID, or an external rod lock.
