About the Airtac SAID80 Double Rod Cylinder SAID80X180
The AirTAC SAID80X180 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80 mm bore and 180 mm stroke. Because the 25 mm rod exits both end covers, the annulus area is identical on extend and retract, yielding exactly 2268 N of thrust and pull force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This through-rod design allows you to mount the primary workpiece on one end while attaching a cam, position flag, or secondary mechanism on the rear rod. The standard carbon steel rod provides durable service, and adjustable air cushions at both ends absorb end-of-stroke kinetic energy. Note that the rear protruding rod requires extra clearance in your machine layout.

Where the Airtac SAID80 Double Rod Cylinder SAID80X180 Is Used
Symmetric Force Transfer
Drives a push-pull shuttle where the 2268 N both-way force at 0.5 MPa must move a heavy carriage equally well in both directions without speed variation.
Dual-Station Actuation
Mounts a forming tool on the front rod end and a part-ejector cam on the rear rod end to operate two sequential workstations simultaneously.
Anti-Rotation Slides
Guides a heavy vertical slide using the twin-rod configuration to prevent torsional twist and maintain precise alignment during retraction.
Is the Airtac SAID80 Double Rod Cylinder SAID80X180 the Right Cylinder?
Choose this 80 mm bore double-rod cylinder when an application demands equal force and speed in both directions, or requires anti-rotation guidance for a symmetric load. Stepping down to the 63 mm bore drops the both-way force to 1402 N at 0.5 MPa, while moving up to the 100 mm bore increases it to 3681 N. Unlike a single-rod SAI cylinder, the SAID80X180 uses a reduced mounting accessory set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants.
This model uses PT G3/8 ports and operates at 30-800 mm/s. Because the stroke is 180 mm, side-load stress on the rod bearing is moderate, but always ensure the load is guided externally for long unsupported strokes. Remember that the air cushions only decelerate the piston near stroke end; they do not hold a load. If pressure drops, the cylinder drifts, so use an external rod lock or a SAIL/BSAID variant for position holding.
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 SAID80X180 FAQ
Because the 25 mm rod occupies both sides of the piston, the effective area is equal in both directions. The cylinder generates 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa on both extend and retract strokes.
Yes, the SAID80X180 is dimensionally interchangeable per ISO 15552 mounting interface dimensions. It uses the standard SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and shares the same PT G3/8 port and 25 mm rod thread as equivalent profile cylinders.
