About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-75S
The AirTAC SAIJ80X160-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 160 mm stroke that can be fine-tuned backward by up to 75 mm, creating an exact 85 to 160 mm usable travel window. Equipped with a -S magnet, it supports position detection via CMSE reed and DMSE electronic sensors.
This model features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads sized at G3/8. The rear adjustment screw acts as a mechanical stop to decelerate the piston at the end of travel; it is not a locking device and will not hold a load without sustained live air pressure. For applications requiring true position holding without air, consider the SAIL or BSAI series instead.

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 SAIJ80AX160-75S Is Used
Variable Product Changeovers
Dial in the exact end-stop for different package lengths on a packaging line, utilizing the wide 85-160 mm travel window to switch products in seconds without changing hardware.
Machine Setup Calibration
Fine-tune the retract end-position during commissioning to achieve perfect alignment, using the rear stopper rather than shimming or altering the standard SAI mounting footprint.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-75S the Right Cylinder?
Select this 80 mm bore cylinder when your application requires substantial force—stepping down to a 63 mm bore reduces push force to 2805 N at 0.9 MPa, while stepping up to a 100 mm bore increases it to 7068 N. The 75 mm adjustment range is exceptionally wide, making this SKU ideal for highly flexible production lines where product sizes change frequently, eliminating the need to physically swap cylinders or add external stops during changeovers.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 160 mm stroke, PT G3/8 ports, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface. Because the 160 mm stroke is relatively short, side-load stress on the 25 mm rod is manageable, but an external guide is still recommended for heavy lateral loads.
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 SAIJ80AX160-75S FAQ
The rear adjuster screw acts as a mechanical stop that limits the piston's retract travel. For this model, you can trim the 160 mm nominal stroke back by up to 75 mm, resulting in a usable travel window of 85 to 160 mm. The standard air cushion decelerates the load at the end of travel, but the adjuster itself does not lock or hold the load without live air pressure.
The maximum operating pressure is 1.0 MPa.
