About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-40S
The AirTAC SAIJ32X225-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 225 mm nominal stroke by up to 40 mm. This creates a precise 185-225 mm usable travel window, perfect for fine-tuning end positions during commissioning without swapping the cylinder.
This variant features an SUS420J2 stainless steel rod for improved corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel provides dual-side sensor grooves compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. It uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.

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 SAIJ32AX225-40S Is Used
Product Changeover
Dial in the 185-225 mm travel window during packaging line format changes to accommodate different carton sizes without changing hardware.
End-Position Tuning
Fine-tune the exact retract position during machine commissioning using the 40 mm rear adjustment screw instead of adding external stoppers.
Sensor Calibration
Leverage the built-in magnet and dual-side sensor grooves to mount CMSE or DMSE switches precisely along the adjusted stroke path.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-40S the Right Cylinder?
The adjustable-stroke design is selected over a fixed SAI when machine setups require variable end-stops or product-size changeovers, letting you trim the travel back by exactly 40 mm rather than adding external mechanical stops. 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 an external rod lock or the SAIL/BSAI series.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 225 mm stroke, 40 mm adjustment, PT G1/8 port, and -S magnet. Because the 225 mm stroke is relatively long for the 12 mm rod diameter, an external guide rail is recommended to prevent excessive side-load wear on the rod seals.
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 SAIJ32AX225-40S FAQ
The rear adjuster screw lets you shorten the 225 mm nominal stroke by up to 40 mm, creating a usable travel window of 185 to 225 mm. The adjuster is a mechanical stop for setting end positions, not a lock, and the cylinder requires live air to hold its load.
