About the Airtac SAID32 Double Rod Cylinder SAID32X120S
The AirTAC SAID32X120-S is a double-acting, double-rod ISO 15552 profile cylinder with a 32mm bore and 120mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on each side, yielding equal push and pull forces of 483 N at 0.7 MPa (345 N at 0.5 MPa). This through-rod geometry provides superior anti-rotation stability over single-rod actuators.
Equipped with a magnet (-S), this variant supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual side grooves on the extruded aluminum barrel. The rear rod extension is ideal for mounting a cam, position flag, or driving a secondary mechanism, while adjustable air cushions at both ends absorb end-of-stroke impact.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID32 Double Rod Cylinder SAID32X120S Is Used
Symmetric Force Transfer
Drives a workpiece from one end while the opposing rod end moves an identical load, maintaining perfectly balanced 483 N force and matching speeds in both directions.
Anti-Rotation Slides
The twin-rod architecture prevents piston rotation during travel, providing precise linear guidance for pick-and-place units without external guide rails.
Rear-Rod Sensing
Mounts a physical cam or DMSE electronic sensor target on the rear protruding rod to trigger secondary mechanisms in compact machinery layouts.
Is the Airtac SAID32 Double Rod Cylinder SAID32X120S the Right Cylinder?
Select this 32mm bore when an application demands symmetric force and speed in both directions, offering 345 N each way at 0.5 MPa. If your mechanism requires less force, stepping down is not an option as 32mm is the minimum bore; stepping up to a 40mm bore increases the both-way output to 528 N at 0.5 MPa. The double-rod design is chosen over a single-rod SAI when twin-station actuation or rear-rod sensing is required.
This model uses PT tapered ports (G1/8) and accepts mounting accessories from the SAID subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that the adjustable air cushion only decelerates the piston near stroke end; it does not hold a load. If position holding without live pressure is needed, use a SAIL lock, BSAID clamp-lock, or external pilot-operated check valve. Dimensionally interchangeable per ISO 15552.
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 SAID32 Double Rod Cylinder SAID32X120S FAQ
Because the rod occupies both sides of the piston, the effective area is equal in both directions. The push and pull force are both 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa.
Yes, it is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses the standard mounting interface but only supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting styles.
