About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-40
The AirTAC SAIJ32X350-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 310-350 mm usable travel window. The rod is constructed from SUS420J2 stainless steel (code A) for enhanced corrosion resistance compared to standard carbon steel.
This adjustable-stroke design allows you to fine-tune the retract end position during commissioning or product changeover without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop and deceleration point, not a load-holding lock. Mounting options are restricted to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32AX350-40 Is Used
End-Position Tuning
Dial in the exact retract position within the 310-350 mm window during machine commissioning without physically swapping out the cylinder.
Product Changeover
Quickly adapt the stroke length on packaging lines handling varying product sizes by turning the rear adjustment screw.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-40 the Right Cylinder?
An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for machine setup or product-size changes on a line. Because the total stroke is 350 mm, the 12 mm rod diameter requires an external guide to prevent excessive side-loading on the unsupported length.
For an exact ISO 15552 replacement, match the 32 mm bore, 350 mm stroke, 40 mm adjustment, PT tapered port threads, SUS420J2 rod material, and the specific mounting accessory. Note that a plain SAIJ does not hold its load without live air pressure; for true load-holding without continuous air, select an AirTAC SAIL or BSAI cylinder 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 SAIJ32AX350-40 FAQ
At 0.9 MPa, the push force increases to 724 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective travel from the nominal 350 mm down to 310 mm. It is a travel stop for end-position tuning, not a load-holding lock.
