About the Airtac SAID32 Double Rod Cylinder SAID32AX250S
The AirTAC SAID32X250-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 250mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding an equal thrust of 483 N at 0.7 MPa on both extend and retract strokes. This through-rod design is highly effective for applications requiring anti-rotation guidance or rear-mounted position flags.
Equipped with a -S magnet, this unit directly supports AirTAC CMSE reed and DMSE solid-state electronic sensors via the dual-side extruded barrel grooves. The rod is constructed from SUS420J2 stainless steel (option A) for enhanced corrosion resistance, and it utilizes PT tapered port threads. Adjustable air cushions at both ends ensure smooth deceleration, though they do not function as a locking mechanism.

| 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 SAID32AX250S Is Used
Anti-Rotation Slides
The twin-rod architecture prevents piston rotation, providing precise linear guidance for sliding mechanisms without needing external guide rods.
Symmetric-Force Transfer
Delivers equal 483 N thrust on both extend and retract strokes at 0.7 MPa, ensuring consistent speed and power for bidirectional transfer systems.
Through-Rod Sensing
The rear rod extension can drive a secondary cam or mount a position flag, pairing with dual-side CMSE/DMSE sensor grooves for precise end-of-stroke detection.
Is the Airtac SAID32 Double Rod Cylinder SAID32AX250S the Right Cylinder?
Choose this 32mm bore double-rod cylinder when your mechanism requires symmetrical force and speed both ways, offering 483 N at 0.7 MPa. If your application needs less thrust, the neighboring 25mm bore SAI series provides a smaller footprint, but the SAID32 is the optimal entry point for ISO 15552 twin-rod anti-rotation tasks. At a 250mm stroke, the unsupported rod length increases; you should incorporate an external guide to prevent rod-bearing bending under heavy side loads.
Unlike a single-rod SAI, this SAID model protrudes from both end covers, requiring extra rear clearance. Remember that a standard SAID does not hold loads without live air pressure—if power is lost, the piston drifts, so integrate a SAIL lock or external pilot-operated check valve for fail-safe positioning. It serves as a direct replacement for any ISO 15552 double-rod cylinder, utilizing the standard Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set.

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 SAID32AX250S FAQ
The double-rod design provides equal force in both directions. It outputs 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, it is dimensionally interchangeable per ISO 15552. It serves as a direct replacement for other ISO 15552 profile double-rod cylinders, utilizing PT ports and the standard SAID mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
