About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX35-20S
The AirTAC SAIJ80X35-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end-position during commissioning. With a nominal 35 mm stroke and a 20 mm adjustment range, it provides a usable travel window of 15 to 35 mm.
This variant includes a SUS420J2 stainless steel rod for enhanced durability against wear and minor environmental exposure. The extruded aluminum barrel features sensor grooves on both sides, and because this is the -S magnet version, it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection. It uses PT tapered port threading and reaches operating speeds of 30-800 mm/s.

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 SAIJ80AX35-20S Is Used
Machine Changeover
Dial in the exact retract position within the 15-35 mm window when switching product sizes on a packaging line, eliminating the need to swap out the entire cylinder.
End-Stop Calibration
Fine-tune the final end position during initial commissioning to perfect a pressing or clamping operation without fabricating custom external spacers.
Sensor-Ready Actuation
Leverage the integrated magnet and dual-side sensor grooves to easily mount CMSE or DMSE switches for precise position feedback in automated assemblies.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX35-20S the Right Cylinder?
Select this 80 mm bore cylinder when your application requires exact end-stop tuning without adding external physical stops. Choose this adjustable-stroke SAIJ model over a fixed-stroke SAI when you anticipate needing to dial in the travel distance during machine setup or product changeovers.
For load-holding requirements without live air pressure, note that the rear adjuster on this cylinder acts only as a travel stop and does not function as a lock or brake. In such cases, consider the SAIL air-released lock or BSAI clamp-lock series instead. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80AX35-20S FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke from its nominal 35 mm down to 15 mm. This provides a 15-35 mm adjustable travel window for fine-tuning the end position at commissioning.
