About the Airtac SAID40 Double Rod Cylinder SAID40X175S
The AirTAC SAID40X175-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 40mm bore and 175mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on both sides, yielding exactly 528 N of force in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
Equipped with a magnet (-S), this variant directly supports AirTAC CMSE reed and DMSE solid-state electronic switches. The twin-rod architecture allows you to drive a primary workpiece on one end while mounting a position flag, cam, or secondary mechanism on the rear rod, delivering superior anti-rotation guidance compared to a single-rod SAI.

Where the Airtac SAID40 Double Rod Cylinder SAID40X175S Is Used
Symmetric Transfer
Drives a workpiece forward and back with identical 528 N force and speed, ensuring stable symmetric transfer without momentum shifts.
Rear-Rod Sensing
Utilizes the protruding rear rod to mount a CMSE or DMSE sensor flag, keeping position feedback completely isolated from the primary work area.
Anti-Rotation Slides
Leverages the dual-rod guidance to prevent piston rotation, making it ideal for precision sliding and lifting mechanisms that reject torsional play.
Is the Airtac SAID40 Double Rod Cylinder SAID40X175S the Right Cylinder?
Select this 40mm bore when an application requires 528 N of symmetric force both ways; if your load demands less thrust, step down to the 32mm bore (345 N), or move up to the 50mm bore (825 N) for heavier transfer. The double-rod design is specifically chosen over a single-rod cylinder when dual-side guidance, anti-rotation resistance, or rear-rod sensing is required. Standard PT tapered port threading is G1/4. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB/CA/CB/CR). This model is dimensionally interchangeable per ISO 15552. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If position holding without live pressure is needed, use an external rod lock or explore the SAIL or BSAID series. For this 175mm stroke, side-load and rod-bearing bending are minimal, but external guides are recommended for long unsupported strokes.
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 SAID40X175S FAQ
It provides 528 N of force at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. Because it is a double-rod cylinder, this force is identical in both extend and retract directions.
Yes, the SAID40X175-S is dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses the standard ISO 15552 mounting interface and accepts standard PT G1/4 tapered ports.
