About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX150-100S
The AirTAC SAIJ80X150-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster.
This specific SKU provides a nominal 150 mm stroke that can be fine-tuned down by up to 100 mm, yielding a highly versatile 50-150 mm usable travel window. It includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and a built-in magnet (-S) compatible with AirTAC CMSE reed and DMSE electronic sensors.

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 SAIJ80AX150-100S Is Used
Product Changeovers
Quickly adapt machinery for varying product sizes by dialing the rear adjuster to shift the 50-150 mm travel window without swapping cylinders.
End-Position Tuning
Achieve precise mechanical endpoints during machine commissioning, using the 100 mm adjustment range to perfect the final approach without adding external stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX150-100S the Right Cylinder?
The generous 100 mm adjustment range is ideal for product changeovers, allowing operators to dial in the exact 50-150 mm travel required.
Remember that the rear adjuster functions strictly as a travel stop, not a locking device; the cylinder cannot hold a load without live air. For load-holding requirements, consider an external rod lock or the AirTAC SAIL series. This model uses PT tapered ports and supports SAIJ mounting options including Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80AX150-100S FAQ
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from its 150 mm nominal length. This creates a flexible 50-150 mm usable travel window for fine-tuning the retract end position during setup.
