Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-30
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-30 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 SAIJ80X130-30
The AirTAC SAIJ80X130-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel end by up to 30 mm. This yields a usable stroke window of 100 to 130 mm, letting you dial in the exact retract position during commissioning or product changeovers without swapping out the barrel or adding external stops. It delivers a robust 2268 N pull force at 0.5 MPa, matching the standard SAI performance class.
The 25 mm carbon steel piston rod and M20x1.5 rod thread provide high rigidity, handling greater side loads than smaller bores, though long unsupported strokes still require an external guide. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock to hold the load without live air.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-30 Is Used
Machine Changeover
Dial in the 100-130 mm retract position during product size changeovers on a packaging line without disassembling the cylinder or adding external stopper blocks.
Variable End Stops
Set precise retract limits for multi-stage tooling operations where the exact end position needs slight tuning per batch or material thickness.
Commissioning Fine-Tune
Trim the travel back by up to 30 mm during initial machine setup to perfect timing and avoid mechanical hard crashes without replacing hardware.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-30 the Right Cylinder?
Select this 80 mm bore when your application requires the 2268 N pull force at 0.5 MPa and needs on-the-fly end-position tuning. If your process demands less force, stepping down to a 63 mm bore yields 1402 N of pull force, while moving up to a 100 mm bore provides 3681 N. The adjustable 100 to 130 mm travel window makes it preferable over a fixed-stroke SAI when accommodating slight variations in product sizes on a line.
This cylinder uses PT tapered port threads and a G3/8 port size. Because it lacks a magnet, it cannot host internal sensors. Remember that the rear adjuster and air cushions only manage travel ends; for true load-holding without live air pressure, you must use a SAIL pneumatic lock, BSAI clamp-lock cylinder, or an external rod lock. Dimensionally interchangeable per ISO 15552, it offers a drop-in footprint for standard mounting interfaces.

- ✓ 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 SAIJ80X130-30 FAQ
At 0.5 MPa operating pressure, the 80 mm bore generates 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
A rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 130 mm down to 100 mm. This creates a 100 to 130 mm usable travel window for fine-tuning the retract end position at commissioning.
