About the Airtac SAID80 Double Rod Cylinder SAID80BX145S
The AirTAC SAID80X145-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 145mm stroke. Because the piston rod exits both end covers, the annular area is identical on both sides, yielding exactly 2268N of thrust and pull force at 0.5MPa in either direction. This symmetric output is ideal for mechanisms requiring equal push and pull speeds.
Equipped with a magnetic piston (-S), it supports position sensing via AirTAC CMSE reed or DMSE electronic switches fitted into the dual-side sensor grooves. The rods are constructed from SUS304 stainless steel (code B) for superior corrosion resistance, and fluid connections use PT tapered threads.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX145S Is Used
Symmetric Force Transfer
Drives equal push and pull loads at 2268N both ways, perfect for shuttle mechanisms requiring identical dynamic response in both travel directions.
Anti-Rotation Slides
The twin SUS304 rods provide enhanced torsional rigidity, guiding heavy vertical slides without the side-play common to single-rod actuators.
Dual-Station Actuation
Mount the primary workpiece on the front rod end and a rear position flag for CMSE/DMSE sensors on the opposing end to sequence separate operations.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX145S the Right Cylinder?
Select this 80mm bore when your application demands more force than the 63mm option (1402N at 0.5MPa) but does not warrant the larger 100mm body. The twin-rod design is chosen over a single-rod SAI when the mechanism requires dual-side guidance to prevent rotation, or when a rear-mounted cam and position flag must drive a secondary station. For mounting, SAID supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, omitting the FB, CA, CB, and CR styles found on single-rod variants.
Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not lock or hold the load. If the system loses air pressure, the cylinder will drift, requiring an external pilot-operated check valve or a BSAID clamp-lock cylinder for secure positioning. As a dimensionally interchangeable ISO 15552 unit, it serves as a direct drop-in replacement for other standard double-rod profile cylinders.
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 SAID80BX145S FAQ
The double-rod design provides equal force in both directions. It delivers 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa for both extend and retract strokes.
Yes, it is a profile cylinder built to ISO 15552 mounting interface dimensions, allowing it to drop in for other standard double-rod cylinders. It uses PT tapered ports and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
