About the Airtac SAID32 Double Rod Cylinder SAID32X400S
The AirTAC SAID32X400-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 400mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 483 N of force both ways at 0.7 MPa. The integrated -S magnet enables position tracking via CMSE reed or DMSE solid-state switches housed in the dual-side sensor grooves.
A rear rod protrusion allows you to mount a cam or secondary position flag opposite the primary workpiece, delivering superior anti-rotation guidance. The carbon steel rod and PT tapered G1/8 porting ensure robust performance across the 30-800 mm/s speed range. Adjustable air cushions at both ends absorb end-of-stroke kinetic energy to protect the mechanism.

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 SAID32X400S Is Used
Symmetric Transfer Unit
Drives a transfer shuttle where the matching extend and retract speeds keep cycle times perfectly balanced without requiring flow controls.
Anti-Rotation Slide
Uses the twin rods exiting both covers to guide a precision slide, preventing yaw and twist without external linear bearings.
Dual-Station Actuation
Mounts the primary workpiece on the front rod end and a secondary cam or limit flag on the rear protrusion to trigger a separate sensor.
Is the Airtac SAID32 Double Rod Cylinder SAID32X400S the Right Cylinder?
Select this 32mm twin-rod unit when an application demands equal push and pull forces alongside dual-side guidance, stepping up from a 32mm single-rod SAI only if you need the larger push-side force. If your mechanism requires less than 345 N at 0.5 MPa, consider dropping to a smaller bore, though 32mm is often the practical minimum for ISO 15552 mounting footprints. The -S magnet is essential here if you need end-of-stroke signaling via CMSE or DMSE switches.
At 400mm of stroke, the unsupported rod length increases bending moments on the rod bearing under side-loads; always use an external guide rail to prevent premature wear. Remember that the adjustable cushions only decelerate the piston near stroke end and do not hold a load if air pressure is lost—use a SAIL or BSAID lock variant if the mechanism must resist drifting when exhausted. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB and CA styles.
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 SAID32X400S FAQ
Because the double-rod design subtracts the rod area on both sides, it provides equal force in both directions: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa.
Yes, the SAID32X400-S is dimensionally interchangeable per ISO 15552 profile standards. It supports mounting accessories from the reduced SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and uses a PT G1/8 port.
