About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-10S
The AirTAC SAIJ32X400-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 390-400 mm usable travel window, allowing you to trim the effective stroke by up to 10 mm during commissioning without swapping the cylinder or bolting on external stops.
This variant includes a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and ships with a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and the PT tapered port threads match the standard G1/8 porting for this bore size. The rear adjuster acts purely as a travel stop, meaning it 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 SAIJ32AX400-10S Is Used
End-Position Tuning
Dial in the exact 390-400 mm retract distance during machine commissioning to perfect product seating without adding external stops.
Product Changeover
Quickly adjust the stroke by up to 10 mm on a packaging line when switching to a slightly different package size.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-10S the Right Cylinder?
Conversely, if you need less force, the SAIJ series does not offer a smaller standard ISO 15552 bore. The adjustable stroke is ideal for product-size changeovers on a line, whereas a fixed-stroke SAI cylinder is preferred when the end position never changes.
Because the 400 mm stroke is relatively long for a 32 mm bore, an external guide is recommended to support the load and prevent excessive side-loading on the 12 mm rod. To replace an ISO 15552 cylinder, match the 32 mm bore, 400 mm stroke, 10 mm adjustment, PT port threads, and the -S magnet. For load-holding without live air, the rear stopper here is not a lock; you would need an external rod lock or a SAIL pneumatic lock cylinder.
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 SAIJ32AX400-10S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 400 mm nominal stroke by up to 10 mm. This provides a usable travel window of 390-400 mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
