About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX950-40S
The AirTAC SAIJ32X950-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 910-950mm usable travel window from its 950mm nominal stroke, allowing you to fine-tune the retract end position during commissioning without adding external stops.
Equipped with a magnet for CMSE reed and DMSE electronic sensors, it integrates seamlessly into position-sensing setups. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions, and the PT tapered ports ensure a tight pneumatic connection. The rear adjuster acts purely as a mechanical stop and does not hold the load without live air pressure.

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 SAIJ32AX950-40S Is Used
Long-Stroke Conveying
Trim the retract distance by up to 40mm to perfectly time the release of parts on a long conveyor belt without swapping cylinders.
Product Changeover
Dial in the exact 910-950mm end-stop during machine changeover to accommodate slightly different product lengths on the fly.
End-Position Tuning
Fine-tune the final retract position during initial machine commissioning to align with existing tooling, avoiding the need for external stopper blocks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX950-40S the Right Cylinder?
Choose this 32mm bore cylinder when you need precise end-position tuning over a long 950mm stroke. If your application requires less force, stepping down is not an option in the SAIJ range as 32mm is the smallest bore, but stepping up to a 40mm bore increases your 0.5MPa push force to 628N. The adjustable stroke is ideal for product changeovers where the exact retract distance varies slightly, unlike a fixed-stroke SAI cylinder. For any stroke of 950mm, the 12mm rod is highly susceptible to side-loading, so an external guide is strongly recommended to prevent binding. This model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. Remember that neither the rear adjuster nor the air cushions function as a lock; for load-holding without live pressure, consider the SAIL or BSAI series.
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 SAIJ32AX950-40S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 40mm, providing a usable travel window between 910mm and 950mm. It acts only as a travel stop and does not lock the load without air pressure.
