About the Airtac SAID80 Double Rod Cylinder SAID80X300S
The AirTAC SAID80X300-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 300mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding equal bidirectional force of 2268N at 0.5MPa and 3175N at 0.7MPa. It includes a standard magnet for position sensing and uses PT tapered port threads with a G3/8 connection.
This design allows mounting a workpiece on one rod end and a cam or position flag on the opposite end to trigger sensors. The extruded aluminum barrel integrates sensor grooves on both sides, accepting AirTAC CMSE reed and DMSE electronic solid-state switches. The standard carbon steel rods provide durable performance, while adjustable air cushions at both ends absorb impact energy near stroke limits.

Where the Airtac SAID80 Double Rod Cylinder SAID80X300S Is Used
Symmetric Force Transfer
Drives a workpiece back and forth with exactly 2268N of force in both directions, ensuring consistent cycle times without push-pull speed variations.
Dual-Station Actuation
Mounts a primary tool on the front rod and a secondary mechanism or cam on the rear rod to operate two synchronized stations from one cylinder.
Anti-Rotation Slides
The twin-rod configuration guides the load against rotational torque better than a single-rod cylinder, maintaining precise alignment for sliding fixtures.
Is the Airtac SAID80 Double Rod Cylinder SAID80X300S the Right Cylinder?
Select this 80mm bore when an application requires symmetric push and pull forces of 2268N at 0.5MPa. Stepping down to a 63mm bore drops the both-way force to 1402N, while moving up to a 100mm bore increases it to 3681N. Choose the double-rod SAID over a single-rod SAI when you need dual-side guidance, anti-rotation stability, or rear-rod actuation. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other standard double-rod profile cylinders.
At 300mm stroke, the extended rod length increases side-load stress on the rod bearing. For heavy off-center loads, use an external guide rail to prevent bending and premature seal wear. Remember that a plain SAID does not hold its position if air pressure drops; use a SAIL lock cylinder or external rod lock for fail-safe load holding. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAID80X300S FAQ
Because the double-rod design subtracts the rod area on both sides, the force is equal in both directions. It provides 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa.
Yes, the SAID80X300-S is a profile cylinder built to ISO 15552 mounting interface dimensions, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a G3/8 port and includes a magnet for CMSE and DMSE sensors.
