About the Airtac SAID32 Double Rod Cylinder SAID32X280S
The AirTAC SAID32X280-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 exactly 483 N of force in both extend and retract directions at 0.7 MPa. This symmetric annulus area ensures identical push and pull dynamics.
Equipped with a magnet (-S), it supports AirTAC CMSE reed and DMSE solid-state electronic sensors via dual-side extruded grooves. The rear rod protrusion is ideal for mounting a cam or position flag, while the PT G1/8 tapered port threads match standard pneumatic fittings.

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 SAID32X280S Is Used
Symmetric Force Transfer
Drives a transfer arm where the 345 N extend and retract forces at 0.5 MPa must be perfectly matched to avoid motor stall or uneven acceleration.
Anti-Rotation Slides
Twin rods exiting both ends prevent the piston from twisting under offset loads, keeping precision tooling perfectly aligned without external guides.
Rear-End Position Sensing
Uses the -S magnet with DMSE solid-state sensors on the rear face while the front rod actuates the primary workpiece, saving space on the main motion axis.
Is the Airtac SAID32 Double Rod Cylinder SAID32X280S the Right Cylinder?
Select this 32mm bore when an application requires equal 483 N thrust both ways at 0.7 MPa, or step down if lower force is acceptable. Choose the SAID twin-rod design over a single-rod SAI when you need dual-side guidance, anti-rotation resistance, or a rear rod end to drive a secondary mechanism. If your mechanism must hold a load without live air pressure, note that this standard cylinder will drift; use an external rod lock or a SAIL/BSAID locking variant instead.
At a 280mm stroke, the unsupported rod length increases bending moments on the rod bearing under side loads. For this configuration, incorporating an external guide rail is recommended to prevent premature wear. It is dimensionally interchangeable per ISO 15552 and uses the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR.

- ✓ 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 SAID32X280S FAQ
Because the rod occupies both sides of the piston, the effective area is identical in both directions. It delivers 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa on both extend and retract strokes.
Yes, the SAID32X280-S is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses standard PT G1/8 ports and supports AirTAC CMSE and DMSE sensors.
