About the Airtac SAID80 Double Rod Cylinder SAID80AX140
The AirTAC SAID80X140 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 140mm stroke. Because the piston rod exits both end covers, the annulus area is identical on both sides, yielding exactly 2268N of force in both extend and retract directions at 0.5 MPa. This symmetric output is ideal for mechanisms requiring perfectly balanced push and pull dynamics.
Equipped with a SUS420J2 stainless steel rod (material code A), this variant provides enhanced corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, though a magnet is not specified for this specific configuration.

Where the Airtac SAID80 Double Rod Cylinder SAID80AX140 Is Used
Symmetric Force Transfer
Drives heavy workpieces requiring identical push and pull forces, utilizing the 2268N both-way capability to maintain consistent motion dynamics without force imbalance.
Anti-Rotation Slides
The twin-rod architecture keeps the load guided and resistant to torsional rotation, replacing bulkier external guide rails in linear sliding fixtures.
Dual-Station Actuation
Mounts a primary workpiece on the front rod end and a secondary mechanism or position flag on the rear protruding rod to synchronize two separate operations.
Is the Airtac SAID80 Double Rod Cylinder SAID80AX140 the Right Cylinder?
Select this 80mm bore when an application demands high symmetric force—stepping down to a 63mm bore drops the both-way output to 1402N at 0.5 MPa, while stepping up to 100mm raises it to 3681N. The twin-rod design is chosen over a single-rod SAI when the rear rod end is needed to mount a cam, drive a secondary mechanism, or provide dual-side anti-rotation guidance. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR options.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. It features PT tapered ports (G3/8) and adjustable air cushions at both ends to decelerate the piston. Note that the air cushion only slows the piston near stroke end; it does not hold the load. If position holding without live air pressure is required, use a BSAID clamp-lock cylinder or an external pilot-operated check valve.
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 SAID80AX140 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It provides an equal force of 2268N in both extend and retract directions at 0.5 MPa, and 3175N at 0.7 MPa.
Yes, the SAID80X140 is an extruded aluminum profile cylinder with standard ISO 15552 mounting dimensions, making it a drop-in replacement for other ISO 15552 double-rod cylinders. Ensure you use the SAID mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
