About the Airtac SAID40 Double Rod Cylinder SAID40BX10S
The AirTAC SAID40X10-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a remarkably short 10mm stroke. Because a SUS304 stainless steel rod exits both end covers, the effective annulus area is identical on extend and retract, yielding an equal 528N of force in both directions at 0.5 MPa. It is dimensionally interchangeable with other ISO 15552 double-rod cylinders.
This compact twin-rod design allows mounting a primary workpiece on the front rod and a position flag or cam on the rear rod. The integrated magnet (-S) enables precise end-of-stroke detection using AirTAC CMSE reed or DMSE solid-state sensors housed in the dual-side barrel grooves.

Where the Airtac SAID40 Double Rod Cylinder SAID40BX10S Is Used
Symmetric Transfer
Drives a dual-sided pick-and-place mechanism where the rear rod simultaneously actuates a secondary ejector, ensuring perfectly synchronized motion.
Anti-Rotation Slide
Utilizes the twin SUS304 rods to guide a heavy fixture rigidly, preventing torsional twist during precise vertical clamping tasks.
Twin-Station Tooling
Mounts a forming tool on one rod end and a limit flag on the opposite end to trigger CMSE/DMSE sensors for process verification.
Is the Airtac SAID40 Double Rod Cylinder SAID40BX10S the Right Cylinder?
Choose this 40mm bore over the 32mm version (345N both ways at 0.5 MPa) when your application demands slightly higher symmetric force, or step up to the 50mm bore (825N) for heavier loads. The double-rod architecture is specifically selected over a single-rod SAI when twin-station actuation or superior anti-rotation guidance is required.
Remember that the adjustable air cushions only decelerate the piston near stroke end; this cylinder will drift and cannot hold a load if air pressure is lost. For position holding without live pressure, consider an external pilot-operated check valve or the BSAID clamp-lock variant. Ensure you specify PT tapered port threads and the correct mounting accessory from the SAID subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
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 SAID40BX10S FAQ
Because the double-rod design subtracts the rod area on both sides, the push and pull forces are equal. It generates 528N in both directions at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa.
Yes, the SAID40X10-S is dimensionally interchangeable per ISO 15552 mounting interface dimensions. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets found on single-rod versions.
