About the Airtac SAID80 Double Rod Cylinder SAID80X45S
The AirTAC SAID80X45-S is a double-acting, double-rod ISO 15552 profile cylinder with a 45mm stroke. Because the piston rod exits both end covers, the effective annulus area is identical on extension and retraction. This provides an equal force of 2268 N in both directions at 0.5 MPa, ensuring perfectly symmetric motion for demanding transfer tasks.
Equipped with a magnetic piston (-S), this carbon-rod variant directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors. The extruded aluminum barrel features sensor grooves on both sides, while the rear rod end can simultaneously drive a primary workload and mount a secondary cam or position flag without requiring extra clearance.

Where the Airtac SAID80 Double Rod Cylinder SAID80X45S Is Used
Symmetric Force Transfer
Ideal for moving payloads between twin conveyor belts where equal push and pull momentum prevents load skewing during bidirectional indexing.
Dual-Station Actuation
Drive a primary clamping tool on the front rod while utilizing the rear rod extension to trip a remote mechanical valve or limit flag.
Anti-Rotation Slides
The twin-rod geometry inherently resists torsional twisting, providing stable guidance for vertical lifting slides without external guide rails.
Is the Airtac SAID80 Double Rod Cylinder SAID80X45S the Right Cylinder?
Select this 80mm bore when an application demands identical push and pull kinetics that a single-rod SAI cannot provide. If your mechanism requires less force, stepping down to the 63mm bore yields 1402 N both ways at 0.5 MPa; stepping up to the 100mm bore provides 3681 N. The integrated magnet allows precise end-of-stroke detection using CMSE or DMSE switches.
This unit uses a PT tapered port thread and accepts mounting accessories from the SAID subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting the FB, CA, CB, and CR styles reserved for single-rod variants). Note that the adjustable air cushions only decelerate the piston near stroke end; they do not lock the load. If air pressure is lost, the cylinder will drift, so use a SAIL lock cylinder or external pilot-operated check valve for position holding.
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 SAID80X45S FAQ
Because the rod occupies both sides of the piston, the push and pull forces are equal. It generates 2268 N both ways at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, the SAID80X45-S is dimensionally interchangeable per ISO 15552. It shares the exact mounting footprint of other profile cylinders, though you must ensure rear-rod clearance is available for the through-rod design.
