About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-40S
The AirTAC SAIJ32X85-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 85 mm stroke that can be dialed back by up to 40 mm, yielding a precise 45-85 mm usable travel window for commissioning flexibility.
Its extruded aluminum barrel includes sensor grooves on both sides, and the PT G1/8 port ensures tapered pneumatic connectivity.

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 SAIJ32AX85-40S Is Used
Machine Changeover
Dial in the 45-85 mm stroke window during product size transitions to set new end positions rapidly without adding external mechanical stops.
End-Position Tuning
Fine-tune the retract end at commissioning using the rear screw, absorbing minor mechanical variances in the fixture layout.
Sensor-Driven Sequencing
Leverage the integrated magnet with DMSE solid-state sensors to confirm the adjusted end-of-stroke position in automated control loops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-40S the Right Cylinder?
Choose this adjustable model over a fixed-stroke SAI when you need variable end-stops for product changeovers without physically swapping cylinders.
Because the stroke is 85 mm, side-load risks are minimal, but the rod diameter and M10x1.25 thread still dictate the acceptable load margins. Remember that the rear adjuster acts only as a travel stop; for true load-holding without live air pressure, consider an SAIL or BSAI cylinder. To match this exact configuration, specify: 32x85 bore and stroke, 40 mm adjustment, PT G1/8 port, Basic/LB/TC mounts, and the -S magnet.
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 SAIJ32AX85-40S FAQ
It can reach a maximum of 82 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the nominal 85 mm stroke by up to 40 mm, creating a 45-85 mm usable travel window. This stopper decelerates the piston at the retract end but does not lock the load without live air.
