About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-30
The AirTAC SAIJ32X45-30 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The built-in rear stopper allows you to trim the nominal 45mm travel back by up to 30mm, creating a highly versatile 15-45mm usable stroke window for exact end-position tuning during machine commissioning.
This adjustable-stroke configuration eliminates the need to swap cylinders or bolt on external stops when refining the retract position. It features a SUS420J2 stainless steel rod for enhanced durability against side loads, and the extruded aluminum barrel includes sensor grooves on both sides. Mounting options include the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ32AX45-30 Is Used
End-Position Tuning
Dial in the exact retract distance within the 15-45mm window during machine setup to perfect pick-and-place timing without changing hardware.
Product Changeovers
Quickly adapt the cylinder's effective stroke on packaging lines when handling different package sizes, using the rear stopper to set new limits.
Assembly Clamping
Apply up to 402N of clamping force at 0.5 MPa while fine-tuning the approach distance to protect delicate components from over-travel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-30 the Right Cylinder?
The SAIJ32X45-30 is selected specifically over a fixed-stroke SAI when product changeovers demand variable end-stops without mechanical rework.
For ISO 15552 replacement matching, verify the 32mm bore, 45mm stroke, 30mm adjustment, PT G1/8 port, and the desired mounting bracket. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding without pressure, consider an AirTAC SAIL or BSAI series 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 SAIJ32AX45-30 FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective travel from the 45mm nominal stroke down to as little as 15mm. This provides a 15-45mm usable window for fine-tuning the retract end position at commissioning.
