About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX140-100
The AirTAC SAIJ80X140-100 is a double-acting ISO 15552 profile cylinder featuring a substantial 100 mm rear stroke adjuster. This external stopper allows you to trim the nominal 140 mm stroke back, creating a wide 40-140 mm usable travel window for highly flexible end-position tuning during commissioning or product changeovers.
This SKU is configured with a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. It uses PT tapered port threads (G3/8) and lacks a piston magnet, meaning it cannot host CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a mechanical travel stop to set deceleration points; it does not lock or hold the load without live air pressure.

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 SAIJ80AX140-100 Is Used
Variable End-Stop Setup
Dial in the exact retraction point between 40 and 140 mm during machine commissioning to perfect pressing depths without physically replacing the cylinder.
Product Size Changeover
Quickly adjust the stroke length on packaging lines to accommodate different carton or product dimensions on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX140-100 the Right Cylinder?
The 100 mm adjustment range is ideal for machinery requiring variable end-stops across different product sizes, negating the need to swap a fixed-stroke SAI cylinder during changeovers. For any load-holding requirements without continuous air pressure, this cylinder is insufficient as the adjuster is only a stop; you should specify a SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
Because the 140 mm stroke is relatively short, side-loading risks are minimal, though the 25 mm rod and M20x1.5 thread provide excellent rigidity and side-load capacity if the cylinder is used in a slightly offset configuration. Ensure your mounting choice comes from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2, as FB, CA, CB, and CR mounts are omitted from this adjustable series.
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 SAIJ80AX140-100 FAQ
The rear adjuster screw lets you mechanically shorten the effective stroke from 140 mm down to as little as 40 mm. This creates a 40-140 mm travel window, allowing precise end-position tuning at commissioning without adding external stops.
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
