About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-75
The AirTAC SAIJ32X135-75 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 135 mm stroke that can be fine-tuned down by up to 75 mm, yielding a highly versatile 60 to 135 mm usable travel window.
This unit features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, allowing for straightforward mounting of position switches if retrofitted later.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 Adjustable Cylinder SAIJ32 SAIJ32AX135-75 Is Used
Machine Changeover
Dial in the 60-135 mm travel window rapidly during product size changes without replacing the cylinder or adding external stops.
End-Stop Calibration
Achieve precise retract end-position tuning at commissioning using the rear adjuster to meet tight manufacturing tolerances.
Variable Positioning
Set custom retract distances on packaging lines for varying material lengths, relying on the rear screw to set the travel limit.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-75 the Right Cylinder?
The 75 mm adjustment range is ideal for product changeovers on a line, functioning as a travel stop rather than a load lock. For holding loads without live air pressure, consider an external pilot-operated check valve or the SAIL locking cylinder.
When replacing an ISO 15552 cylinder, verify the 32 mm bore, 135 mm stroke, 75 mm adjustment requirement, PT G1/8 port, and mounting style. This SAIJ model supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, intentionally omitting FB, CA, CB, and CR brackets. Since the stroke is under 300 mm, side-load stress on the 12 mm rod is minimal, though external guides remain 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 Adjustable Cylinder SAIJ32 SAIJ32AX135-75 FAQ
At 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop that shortens the retract stroke by up to 75 mm. This creates a usable travel window between 60 and 135 mm, allowing you to fine-tune the end position without replacing the cylinder.
