About the Airtac SAID80 Double Rod Cylinder SAID80X115
The AirTAC SAID80X115 is a double-acting, double-rod ISO 15552 profile cylinder. Because a 25mm carbon-steel rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 2268N of force each way at 0.5 MPa. The twin-rod layout provides superior anti-rotation guidance compared to a single-rod SAI, letting you mount the primary workpiece on one end and a cam or position flag on the rear rod.
This 80mm bore unit features a PT G3/8 port and adjustable air cushions at both ends to dampen impact. The extruded aluminum barrel includes dual-side sensor grooves. Without a magnet specified, it relies on external mechanical flags for positioning rather than internal CMSE or DMSE solid-state switches.

Where the Airtac SAID80 Double Rod Cylinder SAID80X115 Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where equal 2268N push and pull capacity is required to move identical payloads in both directions without speed variation.
Anti-Rotation Slides
The twin 25mm carbon-steel rods guide the load against rotation, keeping a vertical lifting slide perfectly aligned throughout the 115mm stroke.
Dual-Side Actuation
Mount a primary gripper on the front rod end and a mechanical limit flag on the rear protruding rod to trigger external sensors.
Is the Airtac SAID80 Double Rod Cylinder SAID80X115 the Right Cylinder?
Choose this 80mm bore when an application demands symmetric push and pull power, stepping up from the 63mm bore which provides 1402N at 0.5 MPa. The SAID80X115 is selected over a single-rod SAI when dual-side actuation or rear-rod sensing is required. Remember that a plain SAID does not hold a load if air pressure drops; the adjustable cushion only decelerates the piston near stroke end. For position holding without live pressure, consider an external rod lock or a BSAID clamp-lock cylinder.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other standard profile double-rod cylinders. It uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB and CA mounts found on single-rod variants. Ensure your layout provides adequate rear-rod clearance, as the rod protrudes from both covers.
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 SAID80X115 FAQ
Because the double-rod design subtracts the 25mm rod area from both sides of the piston, the extend and retract forces are equal. It provides 2268N at 0.5 MPa, 3175N at 0.7 MPa, and 4082N at 0.9 MPa in both directions.
Yes, the SAID80X115 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 that are specific to single-rod SAI cylinders.
