About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-100
The AirTAC SAIJ80X160-100 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 100 mm, yielding a highly versatile 60-160 mm usable travel window. This wide adjustment range is ideal for prototypes or lines running multiple product sizes, allowing you to reposition the end-stop without swapping the actuator.
This model incorporates an SUS420J2 stainless steel piston rod for superior corrosion resistance compared to standard carbon steel. It uses PT tapered port threads (G3/8) and operates at speeds between 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is non-magnetic and will not support AirTAC CMSE reed or DMSE electronic sensors without a magnet. The SAIJ mounting set omits FB, CA, CB, and CR options, utilizing Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.

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 SAIJ80AX160-100 Is Used
Product Size Changeovers
Dial in the exact end-stop for different package lengths on a single conveyor line using the 60-160 mm travel window, minimizing downtime between production runs.
Machine Setup & Prototyping
Fine-tune the retract position during commissioning without machining new spacer blocks or swapping out the entire ISO 15552 actuator.
Variable End-Stop Clamping
Apply up to 2513 N of clamping force at 0.5 MPa while adjusting the clamping depth on the fly to accommodate material thickness variations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-100 the Right Cylinder?
Choose this 80 mm bore when an application demands high thrust (2513 N at 0.5 MPa) alongside extreme stroke flexibility. If you need less force, stepping down to a 63 mm bore yields 1559 N; if your setup requires more power, a 100 mm bore offers 3927 N. The SAIJ80X160-100 is selected over a fixed-stroke SAI cylinder when a machine requires frequent product changeovers, as the 100 mm adjustment screw allows rapid end-position tuning without adding external mechanical stops.
Because the 160 mm stroke is below the 300 mm threshold, external side-load guides are less critical than on longer strokes, though the robust 25 mm rod and M20x1.5 thread handle standard loads well. Remember that the rear adjuster acts only as a travel stop and deceleration aid, not a load-holding lock; the cylinder cannot hold position without live air. For true fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 interchangeable cylinder, specify: 80 mm bore, 160 mm stroke, 100 mm adjustment, PT G3/8 port, desired mounting, and no magnet.
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 SAIJ80AX160-100 FAQ
If operated at 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 160 mm down to 60 mm, creating a 60-160 mm usable window. The adjuster acts as a mechanical stop to tune the end position; it does not lock the load without live air pressure.
