About the Airtac SAID32 Double Rod Cylinder SAID32X20S
The AirTAC SAID32X20-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a compact 20 mm stroke and an integrated magnet for position sensing. Because the piston rod extends from both end covers, the effective annulus area is identical in both directions, yielding an equal push and pull force of 345 N at 0.5 MPa. This symmetric output is ideal for mechanisms requiring consistent dynamics on extension and retraction.
The twin-rod architecture allows you to mount the primary workpiece on the front rod while using the rear protrusion for a cam, position flag, or secondary mechanism. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. It features a standard carbon steel rod and PT tapered port threads.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
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 SAID32X20S Is Used
Symmetric Force Transfer
Drives a transfer arm where the 345 N force must remain identical in both directions, ensuring consistent cycle times without adjusting pressure regulators.
Rear-Rod Cam Actuation
Mounts the primary tool on the front rod while the rear rod end drives a secondary cam or mechanical latch in a compact assembly line station.
Anti-Rotation Guiding
Utilizes the twin-rod structure to resist torsional deflection on a short-stroke clamping jig, maintaining strict parallelism for precision part holding.
Is the Airtac SAID32 Double Rod Cylinder SAID32X20S the Right Cylinder?
Choose this 32 mm bore when an application demands perfectly matched extension and retraction forces within a tight 20 mm stroke, stepping up to the 40 mm bore (528 N at 0.5 MPa) only if higher thrust is required. The double-rod design provides superior anti-rotation resistance compared to a single-rod SAI, making it preferable for guided slides. It uses a reduced mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR options.
As a standard double-acting cylinder, the SAID32X20-S does not hold its position if air pressure is lost; the piston will drift. For load-holding requirements without live pressure, consider an external pilot-operated check valve or the SAIL/BSAID locking variants. Being dimensionally interchangeable per ISO 15552, it serves as a direct replacement for other ISO 15552 double-rod cylinders.

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 SAID32X20S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. It generates 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa in both directions.
Yes, the SAID32X20-S is an extruded aluminum ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses PT tapered ports.
