About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-75
The AirTAC SAIJ80X190-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 190 mm stroke that can be fine-tuned backward by up to 75 mm, yielding a usable travel window of 115 to 190 mm.
This variant incorporates a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet. It is dimensionally interchangeable with ISO 15552 cylinders of the same bore, utilizing a mounting set that includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80AX190-75 Is Used
Product Changeovers
Quickly adjust the travel window from 115 to 190 mm to accommodate varying package sizes on a packaging line without changing hardware.
Machine Setup
Fine-tune the end-of-stroke position during commissioning to achieve precise mechanical alignment without fabricating external stopper blocks.
Variable End Stops
Provide a flexible retraction point for assembly stations where the effective working distance must be dialed in per specific batch requirements.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-75 the Right Cylinder?
Select this 80 mm bore actuator when an application requires substantial thrust—such as the 3518 N generated at 0.7 MPa—combined with variable end-positioning. The 75 mm adjustment range is ideal for product changeovers on a line, allowing operators to dial in the exact stroke length during commissioning without swapping the cylinder or adding external stops. If a smaller footprint is acceptable, a 63 mm bore provides 1559 N at 0.5 MPa; if more force is needed, a 100 mm bore yields 3927 N at the same pressure.
Because the nominal stroke is 190 mm, external side-load guides are not strictly mandated but are recommended for optimal seal longevity. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure; for true load-holding, consider an external rod lock or the AirTAC SAIL series. To replace an existing ISO 15552 unit, match the 80 mm bore, 190 mm stroke, PT ports, and the required mounting style.
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 SAIJ80AX190-75 FAQ
The rear adjusting screw acts as a mechanical stop that shortens the effective travel. For this model, the 190 mm nominal stroke can be dialed back by up to 75 mm, resulting in an adjustable travel window of 115 to 190 mm.
At 0.7 MPa, the push force increases to 3518 N.
