About the Airtac SAID32 Double Rod Cylinder SAID32X550
The AirTAC SAID32X550 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and a 550mm made-to-order stroke. Because a piston rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 483N of force both ways at 0.7 MPa. The G1/8 PT ports and 12mm carbon steel rods keep the unit compact while offering robust dual-side guidance.
This through-rod layout is designed to mount a workpiece on one end and a position flag or cam on the opposite rear rod, delivering superior anti-rotation control. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches (requires a magnet). Adjustable air cushioning at both ends ensures smooth deceleration, though it will not hold a load if air pressure drops.

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 SAID32X550 Is Used
Symmetric Force Transfer
Drives a transfer shuttle where the equal 483N force on both extend and retract strokes ensures perfectly balanced acceleration and deceleration of light workpieces.
Anti-Rotation Slides
Twin 12mm rods completely eliminate piston roll, providing the precise linear guidance required for vertical lifting and pressing jigs without external guides.
Rear-Sensing Actuation
Mounts the primary tool on the front rod while using the protruding rear rod end to trigger a DMSE solid-state sensor, saving space and simplifying wiring.
Is the Airtac SAID32 Double Rod Cylinder SAID32X550 the Right Cylinder?
Select this 32mm bore model when you need equal push and pull forces in a compact footprint, stepping up from a smaller unit or down from a 40mm bore (which offers 528N at 0.5 MPa). The double-rod design is chosen over a single-rod SAI when an application demands twin-station actuation, rear-rod sensing, or strict resistance to torsion. If your mechanism must hold position without live pressure, pair it with an external pilot-operated check valve or choose an SAIL lock variant, as the cushions only decelerate.
Because the 550mm stroke exceeds the 32mm bore's 500mm standard maximum, this is a non-standard, made-to-order configuration with a longer overall length requiring extra rear-rod clearance. At this extended stroke, the 12mm rod is highly susceptible to side-load bending and rod-bearing wear; always use an external guide to support the load and prevent premature seal failure.

- ✓ 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 SAID32X550 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the force is equal in both directions: 345N at 0.5 MPa, 483N at 0.7 MPa, and 621N at 0.9 MPa.
Yes. It is dimensionally interchangeable per ISO 15552 and uses a standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), though it omits FB, CA, CB, and CR brackets.
