About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-40
The AirTAC SAIJ80X200-40 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 40 mm. This creates a highly useful 160-200 mm setup window, letting you dial in the exact retract position during commissioning without swapping out the barrel or adding bulky external stops.
This specific SKU is built with a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and features PT tapered port threads at the G3/8 air supply. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Remember that the rear adjuster functions purely as a travel stop to set end positions; 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 SAIJ80AX200-40 Is Used
Machine Changeover
Dial in the 160-200 mm travel window during product size changes to set new retract positions without replacing the actuator.
End-Stop Calibration
Fine-tune the rear travel limit at commissioning to perfect tooling alignment, avoiding the need for machined spacer shims.
Variable Positioning
Provide a flexible retraction endpoint on automated assembly lines where multiple part sizes are processed on the same station.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-40 the Right Cylinder?
The 40 mm adjustment range is ideal for machinery that undergoes frequent product changeovers, allowing operators to reposition the retract end-stop quickly. If your process requires the cylinder to hold a load statically without continuous air pressure, you should select a SAIL (pneumatic lock) or BSAI (clamp-lock) cylinder instead, as the SAIJ adjuster is only a stop.
When replacing an ISO 15552 cylinder, match these exact parameters: 80 mm bore, 200 mm nominal stroke, 40 mm adjustment range, G3/8 PT ports, and your required mounting bracket from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because this is a single-rod actuator with a 25 mm rod and M20x1.5 thread, it handles side loads well, but any stroke over 300 mm requires an external guide to prevent rod binding.
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 SAIJ80AX200-40 FAQ
It features an external adjusting screw at the rear cap that mechanically shortens the retract stroke by up to 40 mm. This gives you a usable travel window of 160 to 200 mm, allowing precise end-position tuning without changing the cylinder itself.
If you increase the pressure to 0.7 MPa, the push force rises to 3518 N.
