About the Airtac SAID32 Double Rod Cylinder SAID32AX55
The AirTAC SAID32X55 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 55mm stroke. Because the piston rod exits both end covers, the effective annulus area is identical on extend and retract, yielding exactly 345 N of force in both directions at 0.5 MPa. This symmetric output is essential for mechanisms requiring consistent power and speed throughout the cycle.
Equipped with a SUS420J2 stainless steel rod (material code A) and PT tapered port threads, this unit offers robust corrosion resistance for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that a plain SAID relies on live air pressure to maintain position; it will drift if air is lost, so an external rod lock or SAIL variant is needed for holding loads unpowered.

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 SAID32AX55 Is Used
Symmetric Transfer Slide
Drives a pallet transfer unit where the equal 345N extend and retract forces ensure smooth, consistent indexing without speed fluctuations between strokes.
Anti-Rotation Lifter
Lifts a delicate electronic component using a gripper mounted on the front rod while a matching guide shaft on the rear rod prevents mechanical twist.
Twin-Station Actuator
Actuates a small clamping fixture on the front stroke end while simultaneously triggering a rear-mounted mechanical limit valve via the protruding rear rod.
Is the Airtac SAID32 Double Rod Cylinder SAID32AX55 the Right Cylinder?
Choose this 32mm bore when an application demands 345 N of symmetric thrust both ways, such as guiding a transfer slide without rotational twist. If your mechanism requires less force, stepping down is not an option in the ISO 15552 range, but stepping up to a 40mm bore provides 528 N both ways. The double-rod design is specifically selected over a single-rod SAI when you need to mount a cam or position flag on the rear rod, or when dual-side guidance is required to prevent the load from twisting.
This model uses PT ports and accepts AirTAC CMSE reed and DMSE electronic sensors (though a magnet is not specified on this base model, requiring the -S suffix for switch readiness). It is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2. Since the stroke is 55mm, side-load bending stress on the rod bearing is minimal, but always ensure the load is axially aligned to maximize seal life.
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 SAID32AX55 FAQ
Because it is a double-rod cylinder, the force is equal in both directions due to the matching annulus areas. It delivers 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID32X55 is dimensionally interchangeable per ISO 15552 and serves as a direct replacement for other ISO 15552 profile cylinders. Just ensure your mounting accessory falls within the SAID supported set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
