About the Airtac SAID32 Double Rod Cylinder SAID32AX275
The AirTAC SAID32X275 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 275mm stroke. Because a piston rod exits both end covers, the effective annulus area is identical in both directions, yielding an equal push and pull force of 483N at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This configuration is built with a SUS420J2 stainless steel rod for enhanced durability against corrosion and surface wear. It uses PT tapered port threads and lacks a standard magnet, meaning it requires external limit switches or a custom -S variant if electronic or reed sensor feedback is needed. The twin-rod design inherently provides superior anti-rotation guidance compared to single-rod actuators.

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 SAID32AX275 Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where the 483N force and 30-800 mm/s speed must be identical in both directions without recalculating flow or pressure differentials.
Dual-Side Actuation
Mounts the primary workpiece on the front rod and a secondary cam or limit flag on the rear rod end to trigger external mechanical switches during the stroke.
Anti-Rotation Slides
Lifts or pushes a guided plate where the twin 12mm SUS420J2 rods prevent the load from twisting, replacing bulkier linear guide setups in compact spaces.
Is the Airtac SAID32 Double Rod Cylinder SAID32AX275 the Right Cylinder?
Choose the SAID32X275 when an application demands equal bidirectional force and high resistance to torsional load. If your mechanism requires less force, stepping down is an option, but note this 32mm bore already provides the minimum standard force class for this ISO 15552 series at 345N both ways at 0.5 MPa. Select this double-rod variant over a single-rod SAI when you need to mount a position flag or cam on the rear rod end, or when symmetric speed is critical.
At a 275mm stroke, the 12mm rod is subjected to bending moments under heavy side loads; utilizing an external guide rail is recommended to prevent premature rod-bearing wear. This cylinder uses PT ports and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Remember that the adjustable air cushions only decelerate the piston near stroke ends; they do not hold a load. If air pressure drops, the piston will drift. For position holding without live pressure, consider the SAIL or BSAID series.

- ✓ 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 SAID32AX275 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the extend and retract forces are equal. It generates 345N at 0.5 MPa, 483N at 0.7 MPa, and 621N at 0.9 MPa in both directions.
Yes, it is dimensionally interchangeable per ISO 15552. However, the SAID series uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR mounts found on single-rod SAI cylinders.
