About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-30
The AirTAC SAIJ32X400-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 370 to 400 mm usable travel window, allowing you to dial in the retract position precisely during commissioning.
This variant is equipped with an SUS420J2 stainless steel rod (material code A) for improved corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning position sensing requires adding a separate magnetic piston assembly. It supports standard speeds of 30-800 mm/s and uses PT tapered port threads.

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 SAIJ32AX400-30 Is Used
Product Changeovers
Dial in the 370-400 mm travel window during format changes on packaging lines without swapping out the entire actuator.
End-Stop Tuning
Fine-tune the retract position during machine commissioning to avoid mechanical crashes and perfect the end-of-stroke timing.
Variable Diverting
Adjust the stroke length on the fly for pneumatic diverters that handle varying package sizes on a single conveyor belt.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-30 the Right Cylinder?
If your setup needs less force, stepping down is not an option below 32 mm in this series, but stepping up to a 40 mm bore yields 628 N. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. Because the 400 mm stroke is relatively long for this small bore, always use an external guide to prevent rod side-loading and premature seal wear. To match this ISO 15552 footprint exactly, specify the 32 mm bore, 400 mm stroke, 30 mm adjustment, PT port, and the SUS420J2 rod.
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 SAIJ32AX400-30 FAQ
At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the nominal 400 mm stroke by up to 30 mm, creating a 370-400 mm travel window. It acts as a mechanical stop and does not lock the load without continuous air pressure.
