About the Airtac SAID80 Double Rod Cylinder SAID80BX55
The AirTAC SAID80X55 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 55 mm stroke. Because the piston rod extends from both end covers, the effective annulus area is identical on the extend and retract sides. This provides an equal force of 2268 N each way at 0.5 MPa, ensuring perfectly symmetric motion for demanding transfer tasks.
Equipped with a SUS304 stainless steel rod, this variant offers superior corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, while the rear rod end provides a robust platform for mounting a secondary cam, position flag, or driving a second mechanism without interfering with the primary workpiece.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX55 Is Used
Symmetric Transfer
Moves workpieces with identical 2268 N force and speed in both directions, preventing jerk during directional changes in automated lines.
Anti-Rotation Slides
The twin-rod architecture keeps the load guided against rotation better than a single rod, ensuring precise linear tracking without external guides.
Dual-Station Actuation
Mount the primary tool on the front rod and a secondary mechanism or position flag on the rear rod to drive two separate stations simultaneously.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX55 the Right Cylinder?
Select this 80 mm bore when an application requires balanced push and pull forces, as the twin-rod design yields 2268 N in both directions at 0.5 MPa. If your mechanism needs less force, stepping down to the 63 mm bore provides 1402 N both ways. The SAID80X55 is ideal for anti-rotation slides and dual-side guidance, offering better stability than a single-rod SAI cylinder.
This model uses PT tapered ports and supports the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If position holding without live air pressure is required, consider a SAIL lock cylinder, a BSAID clamp-lock, or an external pilot-operated check valve.
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 SAID80BX55 FAQ
The SAID80X55 provides equal force in both directions due to its double-rod design. It delivers 2268 N each way at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, the SAID80X55 is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile cylinders, provided your design accommodates the rear rod protrusion and uses the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting accessories.
