About the Airtac SAID32 Double Rod Cylinder SAID32X70S
The AirTAC SAID32X70-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 70mm stroke. Because the piston rod exits both end covers, the annulus area is identical on both sides, yielding an equal 483N of force in both extend and retract directions at 0.7 MPa. The standard carbon steel rod provides durable service, while the integrated magnet (-S) enables precise position detection.
This through-rod design allows you to mount the primary workpiece on the front rod and a position flag or cam on the rear rod for dual-side sensing. The extruded aluminum barrel includes sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. It uses PT tapered ports and adjustable air cushions at both ends to decelerate the load smoothly.

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 SAID32X70S Is Used
Symmetric Force Transfer
Drives loads where push and pull kinetic energy must match perfectly, utilizing the equal 483N both-way output for stable, balanced motion control.
Dual-Side Sensing
Mounts the primary tool on the front rod extension and a DMSE sensor flag on the rear protruding rod, allowing independent tracking from both ends.
Anti-Rotation Slides
Uses the twin-rod guidance to prevent mechanical twisting on linear slides, ensuring the workpiece remains perfectly aligned without external guides.
Is the Airtac SAID32 Double Rod Cylinder SAID32X70S the Right Cylinder?
Select this 32mm bore when an application demands equal push and pull forces—such as 483N at 0.7 MPa—along with superior anti-rotation guidance. If your mechanism requires higher thrust, stepping up to the 40mm bore neighbor provides 739N both ways, but the SAID32X70-S is ideal for compact, symmetric-force transfer. Unlike a single-rod SAI cylinder, the twin-rod layout prevents the load from twisting during transit.
For direct replacements, match the 32mm bore, 70mm stroke, PT G1/8 port, and mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that the SAID series omits FB, CA, CB, and CR mounts. Because this is a standard double-acting cylinder, it will drift if air pressure is lost; use a SAIL lock cylinder or external pilot-operated check valve if position holding is required.

- ✓ 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 SAID32X70S FAQ
The SAID32X70-S provides equal force in both directions because of the double-rod design. It outputs 345N at 0.5 MPa, 483N at 0.7 MPa, and 621N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID32X70-S is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders by matching the 32mm bore, 70mm stroke, G1/8 port, and appropriate mounting accessories.
