About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-75S
The AirTAC SAIJ32X270-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 270 mm stroke that can be fine-tuned backward by up to 75 mm, yielding a usable travel window of 195-270 mm. The barrel is extruded aluminum with sensor grooves on both sides, and the -S magnet integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors.
This unit features a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and a PT tapered port thread (G1/8). The rear adjuster acts purely as a mechanical stop to decelerate the travel end, meaning it will not hold a load without live air pressure. For applications requiring true load-holding without continuous air, consider the SAIL or BSAI series instead.

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 SAIJ32AX270-75S Is Used
Commissioning Fine-Tuning
Dial in the exact end-position of a 270 mm travel assembly during initial machine setup without adding external physical stops.
Product Size Changeover
Quickly adapt the cylinder's effective stroke from 195 to 270 mm on packaging lines running varying product lengths.
Variable End-Stop Positioning
Use the 75 mm rear adjustment screw to set precise retract positions for multi-format tooling changes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-75S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops or fine-tuning during commissioning without swapping cylinders. Since the total stroke is 270 mm, an external guide is recommended to prevent excessive side-loading on the 12 mm rod.
When replacing an ISO 15552 cylinder, match these exact parameters: 32 mm bore, 270 mm nominal stroke, 75 mm adjustment range, PT tapered G1/8 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ32AX270-75S FAQ
At 0.9 MPa, the push force increases to 724 N.
The rear adjuster screw acts as a mechanical stop that can shorten the 270 mm nominal stroke by up to 75 mm, giving a usable travel window of 195-270 mm. It only sets the end position and does not lock the load without live air pressure.
