Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-20
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 130mm 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 SAIJ80 Adjustable Cylinder SAIJ80X130-20
The AirTAC SAIJ80X130-20 is a double-acting ISO 15552 profile cylinder with a 20 mm rear stroke adjuster. This external stopper lets you dial back the 130 mm nominal stroke, creating a precise 110 to 130 mm usable travel window for exact end-position tuning at commissioning. It delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa.
The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting. The 25 mm carbon steel rod and M20x1.5 thread provide high rigidity, while the rear adjuster acts purely as a travel stop to set the retract endpoint. It does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-20 Is Used
Machine Changeover
Dial in the exact 110 to 130 mm retract endpoint during product size changes without physically swapping the actuator.
End-Position Tuning
Fine-tune the final retract position during commissioning to absorb mechanical tolerances and achieve precise stops.
Variable End Stops
Set a specific travel limit within the 20 mm window for automated assembly lines requiring flexible positioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-20 the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (982 N push at 0.5 MPa) is too weak but a 100 mm bore is oversized. The 20 mm adjustment range is ideal for product changeovers, letting you fine-tune the retract position without swapping the cylinder or adding external stops. For load-holding without live pressure, use an SAIL or BSAI cylinder instead of relying on the adjuster.
This SAIJ model uses PT tapered ports and includes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) that omits FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552. Because the 130 mm stroke is relatively short, side-load risks are minimal, but long unsupported strokes still need an external guide.
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 SAIJ80 Adjustable Cylinder SAIJ80X130-20 FAQ
At 0.5 MPa, it provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 130 mm nominal stroke by up to 20 mm, creating a usable travel window of 110 to 130 mm. It sets the travel end but does not lock or hold the load without live air pressure.
