Airtac SAID32 Double Rod Cylinder SAID32X325S
The AirTAC SAID32 Double Rod Cylinder SAID32X325S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 325mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAID32 Double Rod Cylinder SAID32X325S
The AirTAC SAID32X325-S is a double-acting, double-rod ISO 15552 profile cylinder. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 483 N of force in each direction at 0.7 MPa. The integrated magnet (-S) directly supports rear-side position sensing when paired with AirTAC CMSE reed or DMSE solid-state switches.
This through-rod architecture lets you mount the primary workpiece on the front and a cam, position flag, or secondary mechanism on the rear. The extruded aluminum barrel features sensor grooves on both sides, and the unit omits FB, CA, CB, and CR brackets, utilizing only the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |

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 SAID32X325S Is Used
Symmetric-Force Transfer
Drives a shuttle mechanism where the 483 N push and pull forces must be perfectly matched to prevent motor stall or uneven wear on the guide rails.
Rear-Cam Actuation
Mounts the primary tool on the front rod end and uses the rear rod protrusion to trigger a DMSE solid-state sensor or operate a secondary valve.
Anti-Rotation Slides
Employs the twin-rod geometry to keep a vertical lifting slide perfectly guided against rotation without adding external linear bearings.
Is the Airtac SAID32 Double Rod Cylinder SAID32X325S the Right Cylinder?
Choose this 32mm bore if your application requires equal push and pull forces (483 N at 0.7 MPa) or needs rear-rod anti-rotation guidance. If your mechanism needs less force, stepping down is not an option in the SAI family as 32mm is the smallest bore; stepping up to a 40mm bore raises the both-way force to 528 N at 0.5 MPa. The PT tapered port threads are standard for this size.
Because the 325mm stroke exceeds 300mm, the unsupported rod bearing faces a higher bending moment under side loads; use an external guide rail to prevent premature wear. Remember that the adjustable air cushions only decelerate the piston near stroke end—they do not hold a load. If air pressure drops, the piston will drift; use a SAIL or BSAID lock cylinder for position holding.
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 SAID32X325S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the force is equal in both directions: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. However, as a double-rod variant, it uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR brackets found on single-rod cylinders.
