About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-100
The AirTAC SAIJ80X700-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 100 mm. This creates a highly flexible 600-700 mm usable stroke window, letting you dial in the exact end position during commissioning without swapping out the entire unit.
This 80 mm bore model incorporates a SUS420J2 stainless steel rod for superior corrosion resistance compared to standard carbon steel. It uses PT tapered port threads (G3/8) and relies on a 36 mm air cushion at both ends to decelerate the payload smoothly. Because the rear adjuster acts only as a mechanical stop, it will not hold the load without live air pressure; for fail-safe holding, consider the SAIL or BSAI series.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-100 Is Used
Variable End-Stop Positioning
Set precise rear end positions on a conveyor sorting line, using the 100 mm adjustment window to accommodate different package sizes without reinstalling the cylinder.
Machine Changeover Tuning
Fine-tune the retract stroke during product changeovers, saving setup time by simply turning the rear adjuster screw rather than swapping out mechanical spacers.
Assembly Press Depth Control
Dial in the exact 600 to 700 mm travel needed for an assembly press, ensuring accurate positioning of large components during automated fabrication.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-100 the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when your application requires variable end stops or frequent product-size changeovers on the same line.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 700 mm stroke, 100 mm adjustment range, PT G3/8 ports, and your required mounting interface (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that at 700 mm of travel, the 25 mm rod and M20x1.5 thread still require an external guide to prevent excessive side-loading on the unsupported piston rod.
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 SAIJ80AX700-100 FAQ
The rear adjuster screw acts as a mechanical stop that shortens the retract stroke by up to 100 mm. This gives you a usable travel window between 600 and 700 mm, allowing you to fine-tune the end position without adding external stops.
It operates at speeds between 30 and 800 mm/s and uses a 36 mm air cushion at both ends to decelerate the load.
