About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX90-75S
The AirTAC SAIJ32X90-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet interfaces directly with AirTAC CMSE reed and DMSE electronic switches.
This model utilizes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features PT tapered port threads with a G1/8 connection. The rear screw acts purely as a travel stop to fine-tune deceleration without requiring external stops, though it does not lock the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ32AX90-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract position from 15 to 90mm during machine commissioning without physically swapping the cylinder or adding external stopper blocks.
Product Size Changeover
Quickly adapt the stroke window on packaging lines handling varying product lengths, using the 75mm rear screw to accommodate new formats on the fly.
Sensor-Driven Positioning
Leverage the integrated -S magnet with CMSE or DMSE switches to confirm the adjusted end-of-stroke positions in automated assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX90-75S the Right Cylinder?
Select this 32mm bore when an application requires precise end-position tuning within a 15-90mm travel window, avoiding the need to swap cylinders during product changeovers. For exact ISO 15552 replacement matching, verify the 90mm nominal stroke, 75mm adjuster code, PT port thread, and the -S magnet requirement.
Because the stroke is under 300mm, side-load risks are moderate, but the 12mm rod diameter still requires external guiding for heavy lateral loads. Remember that the rear adjuster and air cushion only manage travel ends; they are not locks. For load-holding without live air, consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ32AX90-75S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to trim the effective stroke by up to 75mm from the nominal 90mm, providing a usable travel window of 15 to 90mm. It acts as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
