About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-20S
The AirTAC SAIJ80X170-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position without adding external stops. It provides a usable travel window of 150-170 mm, trimming the nominal 170 mm stroke by up to 20 mm during commissioning.
This SKU features a SUS420J2 stainless steel rod for improved corrosion resistance and includes a piston magnet for position sensing with AirTAC CMSE reed or DMSE solid-state switches. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions, and the G3/8 PT ports manage pneumatic flow for speeds up to 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 SAIJ80AX170-20S Is Used
Variable End-Stop Tuning
Dial in the exact 150-170 mm travel distance during machine commissioning to accommodate different product sizes without swapping the cylinder.
Product Changeover
Quickly adjust the retract position on packaging lines when switching between box formats, using the 20 mm rear stopper to fine-tune the end point.
Machine Setup
Set precise retraction limits during initial equipment assembly, preventing overtravel and ensuring consistent mechanical positioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-20S the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (offering 825 N pull at 0.5 MPa) lacks the required force, but a 100 mm bore (3681 N pull) would be excessive. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, providing flexibility that a fixed-stroke SAI cylinder cannot match. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. If your application requires true load-holding without continuous air, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock. For strokes of 300 mm or more, always use an external guide to support the load and mitigate side-loading on the 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 SAIJ80AX170-20S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 170 mm nominal stroke down to 150 mm, creating a 150-170 mm usable window for fine-tuning without moving the cylinder.
