About the Airtac SAID80 Double Rod Cylinder SAID80BX425S
The AirTAC SAID80X425-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetric actuation. Because a stainless steel rod exits both ends, the annulus area is identical on each side, yielding an equal 2268N of force in both extend and retract directions at 0.5MPa. This through-rod geometry provides superior anti-rotation stability and permits mounting a secondary tool or position flag on the rear side.
Equipped with a piston magnet (-S), this unit supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side barrel grooves. The SUS304 stainless rods offer excellent corrosion resistance, while the adjustable air cushions at both ends absorb kinetic energy to ensure smooth end-of-stroke deceleration.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX425S Is Used
Symmetric Force Transfer
Drives a workpiece from one end while the opposing rear rod simultaneously shifts a secondary mechanism, ensuring both actions share the identical 2268N force and speed.
Anti-Rotation Slides
The twin-rod architecture prevents the load from twisting during the 425mm traverse, maintaining precise linear guidance for heavy sliding fixtures.
Through-Rod Sensing
Uses the integrated magnet with DMSE electronic sensors on the dual grooves to track position, while the rear rod end can physically trigger an external limit flag.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX425S the Right Cylinder?
Select this 80mm bore when an application requires matched push and pull forces, specifically 2268N at 0.5MPa, which contrasts with the higher push but lower pull of a single-rod SAI cylinder. If your mechanism needs less force, the 63mm bore provides 1402N both ways; if more force is required, stepping up to the 100mm bore yields 3681N. The PT-tapered G3/8 ports and standard 425mm stroke make this model a drop-in replacement for any ISO 15552 double-rod cylinder.
At 425mm of travel, the unsupported rod length increases susceptibility to bending under side loads. Implement an external guide rail to protect the rod bearings and maintain alignment. Note that this cylinder relies on air pressure for movement; it will drift if pressure is lost. For position holding without live pressure, consider an external pilot-operated check valve or the BSAID clamp-lock series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAID80 Double Rod Cylinder SAID80BX425S FAQ
Because the rod occupies both sides of the piston, the effective area is equal in both directions. It provides 2268N of force both extending and retracting at 0.5MPa, and 3175N at 0.7MPa.
Yes, the SAID80X425-S is dimensionally interchangeable per ISO 15552. You can swap it into existing setups using the standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), matching the 425mm stroke and G3/8 ports.
