About the Airtac SAID80 Double Rod Cylinder SAID80BX220S
The AirTAC SAID80X220-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 220 mm stroke and an 80 mm bore. Because the piston rod exits both end covers, the effective annulus area is identical on extension and retraction, yielding an equal push and pull force of 2268 N at 0.5 MPa. This symmetric output is ideal for mechanisms requiring consistent kinetic energy in both travel directions.
Equipped with a magnetic piston (-S), this variant supports position sensing via AirTAC CMSE reed or DMSE electronic solid-state switches fitted into the dual-side sensor grooves. It features a SUS304 stainless steel rod (code B) for superior corrosion resistance, PT tapered port threads, and adjustable air cushions at both ends to decelerate the payload smoothly.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX220S Is Used
Symmetric Force Transfer
Drives equal push and pull loads of 2268 N, ensuring balanced kinetic output for transfer shuttles that perform identical work in both directions.
Anti-Rotation Slides
The twin-rod architecture provides inherent dual-side guidance, preventing piston rotation and maintaining precise alignment for heavy sliding carriages.
Rear-Cam Actuation
The protruding rear rod drives a secondary mechanism or cam, allowing designers to trigger external limit valves independently from the primary front load.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX220S the Right Cylinder?
Select this 80 mm bore when an application demands 2268 N of force in both directions, stepping up from the 50 mm bore (which provides 825 N) or down from the 100 mm bore (3681 N). A double-rod configuration is chosen over a single-rod SAI when the design requires dual-side guidance to prevent rotation, or when a rear cam and position flag must drive a secondary mechanism. Note that the overall length is greater than a single-rod cylinder, requiring rear-rod clearance in your envelope.
This model uses PT port threads and a SUS304 rod. It supports the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). As the 220 mm stroke exceeds 300 mm? No, but at 220 mm it is standard, yet for any long-stroke setup, ensure external guidance to prevent rod-bearing bending. This cylinder is dimensionally interchangeable per ISO 15552. Remember that standard air cushions only decelerate the piston; they do not hold position. If load holding without live pressure is needed, use a BSAID clamp-lock cylinder or an external pilot-operated check valve.

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 SAID80BX220S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa for both extension and retraction.
Yes, it is dimensionally interchangeable per ISO 15552. It shares the standard mounting footprint and uses the SAID accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2), making it a drop-in replacement for other ISO 15552 double-rod cylinders.
