About the Airtac SAID40 Double Rod Cylinder SAID40AX45S
The AirTAC SAID40X45-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 45mm stroke. Because the piston rod extends from both end covers, the effective annulus area is identical on both sides, yielding an equal extend and retract force of 528N at 0.5 MPa. This through-rod geometry provides superior anti-rotation guidance compared to a single-rod SAI.
Equipped with a -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic solid-state sensors mounted along the dual-side grooves of the extruded aluminum barrel. It features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The mounting accessory set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting the FB, CA, CB, and CR variants used on single-rod units.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX45S Is Used
Symmetric-Force Transfer
Drives a shuttle mechanism where the equal 528N push and pull forces ensure consistent acceleration and cycle times regardless of travel direction.
Through-Rod Sensing
Actuates a primary gripper on the front stroke while the rear rod end directly triggers a DMSE electronic sensor flag for precise position confirmation.
Anti-Rotation Slides
Guides a vertical lifting slide using both rod ends to resist torsional twist and prevent binding during compact 45mm strokes.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX45S the Right Cylinder?
Select this 40mm bore when an application demands symmetric force and speed in both directions, offering 528N at 0.5 MPa. If your mechanism requires less force, the 32mm neighbor provides 345N both ways; if more thrust is needed, the 50mm bore offers 825N. The twin-rod design is specifically chosen here to mount a primary workpiece on the front rod end and a position flag or cam on the rear protruding rod, which requires extra clearance behind the rear cover.
For dimensionally interchangeable drop-in replacements per ISO 15552, match the 40mm bore, 45mm stroke, PT port thread, and appropriate mounting accessory. Note that a plain SAID does not hold its position if air pressure is lost; the adjustable air cushions only decelerate the piston near stroke ends. For load-holding requirements without live pressure, consider a SAIL lock cylinder, a BSAID clamp-lock, or an external pilot-operated check valve.
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 SAID40AX45S FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It provides an equal force of 528N at 0.5 MPa, 739N at 0.7 MPa, and 950N at 0.9 MPa for both extending and retracting.
Yes, the SAID40X45-S is dimensionally interchangeable per ISO 15552. You can drop it in for other ISO 15552 double-rod cylinders by matching the 40mm bore, 45mm stroke, and PT port threads, but note it uses the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
