About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX90-40S
The AirTAC SAIJ32X90-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 90 mm stroke that can be dialed back by up to 40 mm, giving technicians a precise 50-90 mm usable travel window for commissioning without external stops.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear adjuster functions strictly as a travel stop, not a load lock.

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 SAIJ32AX90-40S Is Used
Machine Changeover
Dial in the 50-90 mm stroke window during product size changes to set new end positions rapidly without swapping out the entire cylinder.
End-Stop Tuning
Fine-tune the final retract position at machine commissioning to perfect part seating, avoiding the need to bolt on external physical stops.
Sensor Integration
Leverage the built-in magnet and dual sensor grooves to easily mount CMSE or DMSE switches for precise position feedback in compact assemblies.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX90-40S the Right Cylinder?
The adjustable 50-90 mm travel window is perfect for product changeovers, whereas a fixed SAI cylinder locks you into a single 90 mm dimension. For exact ISO 15552 replacement matching, verify the 90 mm stroke, 40 mm adjuster code, PT tapered port thread, and the -S magnet requirement.
Because the stroke is under 300 mm, side-load stress on the 12 mm rod is manageable, but always guide the load externally. Remember that the rear stopper only sets the travel end; it cannot hold the load without live air pressure. For true pneumatic locking without continuous air, consider the SAIL or BSAI series instead. Mounting options include 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 Adjustable Cylinder SAIJ32 SAIJ32AX90-40S FAQ
If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm from the 90 mm nominal length, creating a 50-90 mm usable travel window. The adjuster acts as a physical stop and does not lock the load without continuous air pressure.
