About the Airtac SAID80 Double Rod Cylinder SAID80X220
The AirTAC SAID80X220 is a double-acting, double-rod ISO 15552 profile cylinder with a 80 mm bore and 220 mm stroke. Because a carbon steel rod extends from both end covers, the annulus area is identical on each side. This yields perfectly balanced performance, generating 2268 N of force at 0.5 MPa on both the extend and retract strokes. The cylinder features a PT G3/8 port and operates at 30-800 mm/s.
This through-rod design allows you to mount the primary workpiece on one end and attach a position flag, cam, or secondary mechanism to the rear. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Without a magnet specified, it relies on external physical flags, and the adjustable air cushions at both ends decelerate the piston smoothly near stroke end.

Where the Airtac SAID80 Double Rod Cylinder SAID80X220 Is Used
Symmetric Force Transfer
Ideal for pressing or transferring loads where the push and pull forces must be exactly equal, utilizing the 2268 N both-way output at 0.5 MPa.
Anti-Rotation Slides
The twin-rod design prevents piston rotation, providing stable guidance for precision sliding mechanisms and lifting stages.
Through-Rod Sensing
Mount a physical cam or limit flag on the protruding rear rod to trigger external sensors, since no internal magnet is specified for this unit.
Is the Airtac SAID80 Double Rod Cylinder SAID80X220 the Right Cylinder?
Choose this 80 mm bore when an application demands symmetric force and speed in both directions, offering 2268 N at 0.5 MPa. If your project requires less force, stepping down to the 63 mm bore provides 1402 N both ways. Stepping up to the 100 mm bore yields 3681 N. The double-rod architecture is selected over a single-rod SAI when dual-side guidance, anti-rotation stability, or rear-end sensing is required.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR variants. Note that a plain SAID does not hold a load if air pressure is lost; for fail-safe holding, consider an external rod lock or the BSAID clamp-lock variant. Because the stroke is 220 mm, ensure the rear rod has adequate clearance and use an external guide to prevent rod-bearing bending under heavy side loads.
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 SAID80X220 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, 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.
Yes, it is dimensionally interchangeable per ISO 15552. However, it uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits the FB, CA, CB, and CR mounts found on single-rod variants.
