Airtac SAID80 Double Rod Cylinder SAID80X450
The AirTAC Airtac SAID80 Double Rod Cylinder SAID80X450 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 450mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAID80 Double Rod Cylinder SAID80X450
The AirTAC SAID80X450 is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetric actuation. Because a 25 mm carbon steel rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal force of 2268 N each way at 0.5 MPa. This through-rod design provides superior anti-rotation guidance and allows mounting a secondary cam or position flag on the rear extension.
Built with an extruded aluminum barrel featuring dual sensor grooves, the unit operates at speeds of 30-800 mm/s. It utilizes adjustable air cushions at both ends to decelerate the piston smoothly. Fluid must be filtered to 40 um, and porting is PT (tapered) G3/8. For applications requiring position holding without live air pressure, consider the SAIL or BSAID locking variants.

Where the Airtac SAID80 Double Rod Cylinder SAID80X450 Is Used
Symmetric Force Transfer
Drives dual-station mechanisms where the 2268 N output must remain perfectly balanced in both directions without relying on differential push and pull areas.
Anti-Rotation Slides
Utilizes the twin 25 mm carbon steel rods exiting both ends to maintain strict linear guidance and prevent workpiece twist during heavy handling.
Through-Rod Sensing
Mounts a cam or physical limit flag on the rear rod protrusion to trigger external proximity sensors, keeping the primary work area clear of obstructions.
Is the Airtac SAID80 Double Rod Cylinder SAID80X450 the Right Cylinder?
Selecting this 80 mm bore over the smaller 63 mm (1402 N at 0.5 MPa) provides a significant force upgrade to 2268 N both ways, while stepping up to the 100 mm bore yields 3681 N. The double-rod architecture is chosen over a single-rod SAI when the mechanism requires twin-station actuation, dual-side guidance against rotation, or rear-rod sensing. It is dimensionally interchangeable per ISO 15552 mounting interfaces.
For a drop-in replacement, match the 80 mm bore, 450 mm stroke, PT G3/8 ports, and the correct mounting accessory from the SAID subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (FB, CA, CB, and CR are excluded). Note that this unit lacks a magnet; adding the -S suffix enables CMSE reed and DMSE electronic sensors. Because the stroke is 450 mm, the long unsupported rod bearing is susceptible to bending under lateral loads—always use an external guide to prevent premature seal wear.
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 SAID80X450 FAQ
The SAID80X450 delivers equal force in both directions due to its double-rod design. It provides 2268 N each way at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552 profile cylinder standards. Just match the 80 mm bore, 450 mm stroke, PT G3/8 ports, and ensure you use the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) as FB, CA, CB, and CR are not supported.
