About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-30
The AirTAC SAIJ32X45-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 15-45mm usable travel window, letting you dial in the exact end position without swapping hardware. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/8 connection. The rear stopper screw acts purely as a travel limit and relies on the integrated air cushion for deceleration; it does not lock the load without continuous air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-30 Is Used
Short-Stroke Tuning
Dial in the exact 15-45mm travel limit during machine commissioning to perfect part seating or clamping depth without machining new spacers.
Product Changeover
Quickly adjust the retract end-stop on packaging lines when switching between slightly different product sizes or thicknesses.
Corrosive Assembly
Leverage the SUS304 stainless steel rod for light-duty assembly tasks in environments where moisture or mild chemicals are present.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-30 the Right Cylinder?
Choose this 32mm bore when an application requires fine-tuning of a short 15-45mm stroke during setup or product changeover, rather than committing to a fixed-length SAI cylinder. If your process needs more thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. Because the stroke is under 300mm, side-load stress on the 12mm rod is minimal, though external guides remain best practice for rigid loads.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm a 32mm bore, 45mm nominal stroke, 30mm adjustment range, PT G1/8 port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting. Note that SAIJ omits the FB, CA, CB, and CR mounts. For load-holding without live air, select an external rod lock or pilot-operated check valve, as the adjuster is not a brake.
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 SAIJ32BX45-30 FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. If operated at 0.7 MPa, the push force increases to 563N.
The rear adjuster screw lets you trim the nominal 45mm stroke back by up to 30mm, creating a 15-45mm usable travel window. It functions as a physical stop and does not lock the load without live air pressure.
