About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-75S
The AirTAC SAIJ80X170-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches.
This specific SKU provides a nominal 170mm stroke that can be dialed back by up to 75mm, creating a highly flexible 95-170mm usable travel window. It utilizes a SUS420J2 stainless steel rod for improved corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for convenient switch mounting.

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 SAIJ80AX170-75S Is Used
Product Changeovers
Dial in the 95-170mm travel window during format size changes on a packaging line without replacing hardware.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to achieve exact positioning without external shims.
Variable End Stops
Provide adaptable physical stops for assembly presses requiring different retract depths per batch.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-75S the Right Cylinder?
If you need less force, the 63mm bore offers 1559N; if you need more, the 100mm bore provides 3927N. The 75mm adjustment range is ideal for product-size changeovers on a line, allowing you to fine-tune the retract position at commissioning without swapping the cylinder or adding external stops.
For an exact ISO 15552 replacement match, verify the 80mm bore, 170mm nominal stroke, 75mm adjustment range, PT ports, and the -S magnet. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300mm, side-load risks are moderate, but the 25mm rod still requires external guiding for heavy lateral loads. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for locking, use SAIL or BSAI types.
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 SAIJ80AX170-75S FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the 170mm nominal stroke by up to 75mm, resulting in a usable travel window of 95-170mm. The adjuster acts as a mechanical stop to set the end position and does not lock the load without air pressure.
