About the Airtac SAID80 Double Rod Cylinder SAID80X325S
The AirTAC SAID80X325-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a built-in magnet for position sensing. Because the piston rod extends through both end covers, the annular area is identical on extend and retract, yielding exactly 2268 N of force in both directions at 0.5 MPa. The carbon steel rod provides durable performance, while the -S magnet integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves.
This through-rod design allows you to mount the primary workpiece on one end and attach a position flag, cam, or secondary mechanism on the rear rod end. The twin-rod architecture also provides superior anti-rotation guidance compared to a single-rod SAI cylinder. Adjustable air cushions at both ends decelerate the piston near stroke end, but note that this cylinder will drift if air pressure is lost and does not function as a lock.

Where the Airtac SAID80 Double Rod Cylinder SAID80X325S Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where the equal 2268 N push and pull forces at 0.5 MPa ensure consistent momentum and cycle times in both travel directions.
Dual-Side Actuation
Mounts a primary tool on the front rod and a secondary cam or position flag on the rear rod end to trigger external reed or solid-state sensors.
Anti-Rotation Slides
Utilizes the twin-rod through-body design to guide a heavy sliding carriage, preventing rotation without requiring external guide shafts.
Is the Airtac SAID80 Double Rod Cylinder SAID80X325S the Right Cylinder?
Choose this 80mm bore double-rod cylinder when an application requires symmetric push and pull forces of 2268 N at 0.5 MPa, along with dual-side guidance. If your mechanism needs less force, step down to the 63mm bore SAID, which provides 1402 N each way. If you require more power, the 100mm bore SAID offers 3681 N in both directions. The PT tapered port thread is G3/8 for this bore size.
At 325mm of stroke, the unsupported rod length is significant. To prevent rod-bearing bending and premature seal wear under side loads, always use an external guide rail. This SAID80X325-S is dimensionally interchangeable per ISO 15552, making it a drop-in replacement for other ISO 15552 double-rod cylinders. It supports the reduced SAID mounting accessory set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAID80X325S FAQ
Because the rod occupies both sides of the piston, the effective area is the same in both directions. It delivers 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa on both extend and retract strokes.
No, the adjustable air cushions only decelerate the piston near the stroke ends and do not lock the load. If you need position holding without live air pressure, consider an external rod lock, a pilot-operated check valve, or the AirTAC SAIL and BSAID locking cylinder variants.
