About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-75
The AirTAC SAIJ80X130-75 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This specific SKU features a SUS420J2 stainless steel rod (A code) for enhanced corrosion resistance and uses PT tapered port threads.
The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning or product changeovers. It is not a locking device and cannot hold a load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series instead. This cylinder supports a speed range of 30-800 mm/s and includes variable air cushions at both ends to manage kinetic energy.

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 SAIJ80AX130-75 Is Used
Variable End-Stop Tuning
Dial in the exact retract position from 55 to 130 mm during setup, eliminating the need for external stopper blocks on the machine frame.
Product Size Changeovers
Quickly adapt the cylinder stroke on packaging or sorting lines when switching to a different product length, minimizing downtime.
Commissioning Calibration
Fine-tune the end-of-stroke position at startup to perfectly time machine sequencing without physically remounting the actuator.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-75 the Right Cylinder?
The 75mm adjustment range is exceptionally wide, making this model ideal for machines processing highly variable product sizes where the end-stop needs frequent recalibration.
Because the 130mm stroke is relatively short, side-load stress is minimal, though long unsupported strokes should always use an external guide. When replacing an ISO 15552 cylinder, match the 80mm bore, 130mm nominal stroke, 75mm adjustment, PT G3/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this version omits the -S magnet, so position sensing requires external switches.
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 SAIJ80AX130-75 FAQ
It can achieve a maximum push force of 513 kgf at 1.0 MPa.
The rear mechanical adjuster allows you to trim the effective stroke back by up to 75 mm from the 130mm nominal length, creating a usable travel window of 55 to 130 mm. The adjuster acts as a travel stop and does not lock the load without air pressure.
