About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-30
The AirTAC SAIJ80X60-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to shorten the effective travel. With a 60mm nominal stroke and a 30mm adjustment screw, you get a highly flexible 30-60mm usable travel window for precise end-position tuning at commissioning. This bore delivers substantial force, offering 2513N of push thrust and 2268N of pull thrust at 0.5 MPa.\n\nBuilt with a SUS420J2 stainless steel rod for enhanced corrosion resistance, this model uses PT tapered ports sized at G3/8. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches. The rear adjuster acts purely as a mechanical stop to set the retract end position, meaning it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-30 Is Used
Machine Changeover
Dial in the 30-60mm travel window during product size changeovers to set new retract end positions without physically swapping the cylinder.
End-Position Tuning
Fine-tune the exact retract stroke limit during machine commissioning to compensate for mechanical tolerances in the fixture.
Variable End Stops
Use the rear adjuster screw to set different stroke limits for multiple operations running on the same 80mm bore pneumatic station.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-30 the Right Cylinder?
Choose this 80mm bore adjustable-stroke cylinder when your application requires 2513N of push force at 0.5 MPa but exact end-positioning varies per job. If you need less force, stepping down to a 63mm bore yields 1559N, while moving up to a 100mm bore provides 3927N. The SAIJ80X60-30 is selected over a fixed SAI cylinder when you need to dial in a specific travel window between 30 and 60mm without adding external stops or swapping the cylinder during product changeovers.\n\nBecause the stroke is relatively short at 60mm, side-load stress on the 25mm rod is minimal, but an external guide is always recommended for heavy loads. This model uses a reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 mounting interfaces.
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 SAIJ80AX60-30 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push thrust and 2268N of pull thrust. At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw lets you trim the 60mm nominal stroke back by up to 30mm, creating a usable travel window between 30mm and 60mm. The adjuster acts as a mechanical stop for the retract end and does not function as a lock to hold the load without live air.
