About the Airtac SAID32 Double Rod Cylinder SAID32X145S
The AirTAC SAID32X145-S is a double-acting, double-rod ISO 15552 profile cylinder. A single piston drives a carbon steel rod out of both end covers, yielding perfectly symmetric force and speed. It generates 483N of thrust and pull simultaneously at 0.7 MPa.
Because this variant includes a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic sensors along the dual side grooves. The through-rod design is ideal for mounting a primary workpiece on the front while tracking a position flag or driving a secondary cam on the rear. It uses PT tapered ports sized G1/8.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
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 SAID32X145S Is Used
Symmetric Force Transfer
Pushes and pulls a workpiece between two stations with identical 483N force, preventing speed fluctuations caused by uneven piston areas.
Dual-Station Actuation
Drives a primary tool on the front rod extension while simultaneously operating a secondary valve or mechanism from the rear rod end.
Anti-Rotation Guidance
Keeps a delicate gripper perfectly aligned during a 145mm traverse, using the twin rods to resist torsional twisting better than a single profile cylinder.
Is the Airtac SAID32 Double Rod Cylinder SAID32X145S the Right Cylinder?
Select this 32mm bore when an application requires equal 483N force in both directions, stepping down from the 40mm bore (which offers 739N at 0.5 MPa) for tighter spaces. The twin-rod architecture provides superior anti-rotation guidance compared to a single-rod SAI, supporting dual-side loads. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold the load. If position holding without live air pressure is required, use a SAIL lock cylinder or an external pilot-operated check valve.
As a dimensionally interchangeable ISO 15552 component, it serves as a direct replacement for other standard profile cylinders. It uses a reduced mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets found on single-rod versions.
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 SAID32X145S FAQ
Because the rod occupies both sides of the piston, the effective annulus area is identical in both directions. It outputs 345N at 0.5 MPa, 483N at 0.7 MPa, and 621N at 0.9 MPa for both extension and retraction.
Yes, it is dimensionally interchangeable per ISO 15552. However, the double-rod design uses a specific subset of brackets: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It does not support the FB, CA, CB, or CR mounts found on single-rod cylinders.
