About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-40S
The AirTAC SAIJ32X300-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 40 mm. This creates a usable 260-300 mm adjustable window, letting you dial in the exact end position during commissioning without adding external stops.
Equipped with a magnet for position sensing, this unit works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches fitted into the dual-side sensor grooves on the extruded aluminum barrel. The rod thread is M10x1.25 and the port is PT tapered. Remember the rear adjuster acts only as a travel stop and deceleration aid, not a load-holding lock; it will not hold the payload 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 SAIJ32AX300-40S Is Used
Machine Setup Tuning
Dial in the exact 260-300 mm retract position during commissioning to perfectly align a pusher plate without machining custom spacers.
Product Size Changeover
Quickly adjust the stroke stopper when the packaging line switches to a different carton length, minimizing downtime between production runs.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-40S the Right Cylinder?
Choose this 32 mm bore when you need precise variable end-stops for product changeovers on a packaging line. The SAIJ32X300-40-S is selected over a fixed-stroke SAI when machine setups demand a variable end-stop, allowing you to fine-tune the retract position on the fly rather than swapping cylinders.
Because this unit features a 300 mm stroke, the 12 mm rod requires external guidance to prevent side-load damage on long unsupported extensions. It is dimensionally interchangeable per ISO 15552 with competing profile cylinders, configured here with a PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and a -S magnet. For applications requiring true load-holding without live air, consider the SAIL or BSAI series 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 SAIJ32AX300-40S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the 300 mm nominal stroke by up to 40 mm, providing a usable travel window of 260-300 mm. It functions as a travel stop and does not lock or hold the load without continuous air pressure.
