About the Airtac SAID40 Double Rod Cylinder SAID40BX1000S
The AirTAC SAID40X1000-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and a 1000mm made-to-order stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding an equal push and pull force of 528N at 0.5 MPa. A rod protrudes from both end covers to provide superior anti-rotation guidance and allow mounting a secondary tool or sensor flag at the rear.
This variant includes a magnetic piston for position sensing with CMSE reed or DMSE solid-state switches. It features SUS304 stainless steel rods for corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and adjustable air cushions at both ends decelerate the piston near stroke end.

Where the Airtac SAID40 Double Rod Cylinder SAID40BX1000S Is Used
Symmetric Force Transfer
Moves workpieces with identical push and pull thrust, ensuring consistent speed and force dynamics regardless of the travel direction.
Anti-Rotation Slides
The twin SUS304 rods keep the load guided and prevent rotation during long 1000mm traverses without needing external guides.
Dual-Station Actuation
Drives a primary workpiece on the front rod while a rear-mounted cam or flag triggers CMSE/DMSE sensors for secondary timing.
Is the Airtac SAID40 Double Rod Cylinder SAID40BX1000S the Right Cylinder?
Select this 40mm bore model when your application requires equal force and speed in both directions, offering 528N at 0.5 MPa. If your mechanism needs less force, stepping down to a 32mm bore provides 345N both ways; stepping up to a 50mm bore yields 825N. The double-rod design is chosen over a single-rod SAI when twin-station actuation or rear-side sensing is required.
This cylinder uses a G1/4 port and supports mountings Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). It is dimensionally interchangeable per ISO 15552. Note that the 1000mm stroke exceeds the 800mm standard maximum, making it a non-standard made-to-order part. Because the stroke is 300mm or more, the long unsupported rod is prone to bearing bending under side-loads; always use an external guide rail. This plain cylinder does not hold position if air pressure is lost—use SAIL or BSAID for locking needs.
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 SAID40 Double Rod Cylinder SAID40BX1000S FAQ
Because the double-rod design subtracts the rod area on both sides, the extend and retract forces are equal. It provides 528N at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa in both directions.
Yes, the SAID profile cylinder is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 double-rod cylinders, matching the standard 40mm bore mounting interface and G1/4 port.
