About the Airtac SAID32 Double Rod Cylinder SAID32X425
The AirTAC SAID32X425 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32 mm bore and 425 mm stroke. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding a balanced 345 N of force in each direction at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on two sides for flexible switch mounting.
This through-rod layout lets you attach a workpiece on the front end and a cam or position flag on the rear to trigger external sensors. It uses adjustable air cushioning at both ends to decelerate the piston, but note that a plain SAID will drift if air pressure is lost and cannot hold a load without an external rod lock or pilot-operated check valve.

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 SAID32X425 Is Used
Symmetric Force Transfer
Drives a press or clamping fixture where the 345 N extend and retract forces must be perfectly equal, preventing directional force bias.
Anti-Rotation Slides
Guides a vertical lifting slide using twin rods exiting both ends to keep the load locked against rotational torque without external guides.
Rear-End Sensing
Actuates a part handler while the protruding rear rod drives a physical cam flag to trigger external mechanical limit sensors.
Is the Airtac SAID32 Double Rod Cylinder SAID32X425 the Right Cylinder?
Select this 32 mm bore model when your mechanism requires equal push and pull forces—stepping down from a 40 mm bore halves your force to 528 N at 0.5 MPa, while stepping up to a 50 mm bore increases it to 825 N. Choose the SAID double-rod configuration over a single-rod SAI when you need dual-side guidance, anti-rotation control, or rear-rod actuation. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
With a 425 mm stroke, the unsupported piston rod is highly susceptible to bending and side-load stress. Always use an external guide to prevent rod-bearing damage. This cylinder is dimensionally interchangeable per ISO 15552 and uses a PT tapered port thread. Since no magnet is specified, add an -S suffix if you require CMSE reed or DMSE solid-state sensors.

- ✓ 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 SAID32X425 FAQ
The SAID32X425 provides 345 N of force at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. Because it is a double-rod cylinder, this force is identical in both the extend and retract directions.
Yes, the SAID32X425 is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses the standard ISO 15552 mounting interface and accepts Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting accessories.
