About the Airtac SAID80 Double Rod Cylinder SAID80X260S
The AirTAC SAID80X260-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80 mm bore and 260 mm stroke. A single piston drives a carbon steel rod out of both end covers, yielding equal extend and retract forces. Because the annulus area is identical on both sides, you get 2268 N of thrust and pull each way at 0.5 MPa, climbing to 3175 N at 0.7 MPa. The integrated -S magnet enables position tracking via CMSE reed or DMSE electronic solid-state switches fitted into the dual-side sensor grooves.
Choosing this through-rod layout allows you to mount the primary workpiece on one end while attaching a mechanical cam, secondary tool, or limit flag to the opposite rear rod end. It provides superior anti-rotation guidance for the load compared to a single-rod unit. The adjustable air cushions at both ends absorb end-of-stroke impact, but note that this plain cylinder will drift if air pressure is lost and cannot hold a load without an external pilot-operated check valve or lock.

Where the Airtac SAID80 Double Rod Cylinder SAID80X260S Is Used
Symmetric Force Transfer
Ideal for shuttle mechanisms requiring identical push and pull kinetics, using the twin rods to move a load back and forth without the speed variance seen in single-rod setups.
Dual-Station Actuation
Drive a primary tool on the front rod face while utilizing the rear rod extension to trip a mechanical limit flag or actuate a secondary mechanism simultaneously.
Anti-Rotation Slides
The through-rod construction offers enhanced torsional resistance, keeping vertical lifting slides and guided presses perfectly aligned without rotational drift.
Is the Airtac SAID80 Double Rod Cylinder SAID80X260S the Right Cylinder?
Select this 80 mm bore when your application demands symmetric force and speed in both travel directions, requiring 2268 N at 0.5 MPa. If your mechanism needs less force, stepping down to the 63 mm bore yields 1402 N each way; conversely, moving up to the 100 mm bore provides 3681 N. The SAID80X260-S is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders. To match your build, confirm the 260 mm stroke, G3/8 PT ports, and compatible mounting accessories from the SAID set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
Because the stroke is 260 mm, the unsupported rod length increases bending moments and side-load stress on the rod bearing. For optimal longevity and to prevent premature seal wear, use an external guide rail to support the load rather than relying solely on the piston rod. The extruded aluminum barrel design keeps the assembly lightweight while maintaining structural rigidity.

- ✓ 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 SAID80X260S FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides of the piston. It outputs 2268 N in both extend and retract directions at 0.5 MPa, and 3175 N at 0.7 MPa.
No, the adjustable air cushions only decelerate the piston near the stroke ends and do not act as a brake. The piston will drift if air is exhausted. For fail-safe load holding, consider an AirTAC SAIL or BSAID clamp-lock cylinder, or use an external rod lock.
