About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-30
The AirTAC SAIJ32X105-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 105 mm travel by up to 30 mm. This creates a usable 75-105 mm end-position window for fine-tuning during commissioning without adding external stops. In the compact 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. Because no magnet is specified, position sensing requires adding the -S option to support CMSE reed or DMSE electronic switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-30 Is Used
Machine Changeover
Quickly dial in the 75-105 mm stroke window during product size changes on a packaging line without swapping out the entire cylinder.
Variable End-Stop
Use the rear adjuster to set precise retract positions for light-duty assembly tasks, accommodating multiple part heights on the same fixture.
Commissioning Fine-Tune
Trim the nominal 105 mm stroke by up to 30 mm during initial setup to perfectly time machine sequencing and avoid mechanical hard stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-30 the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning in a compact footprint; if your application requires greater thrust, stepping up to the 40 mm bore provides 628 N of push force at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops or frequent product changeovers, whereas a fixed SAI cylinder is better for rigid, unchanging travel limits.
Remember that the rear adjuster functions strictly as a travel stop, not a locking device, so it will not hold a load without live air pressure. For load-holding without continuous air, consider an external rod lock, a pilot-operated check valve, or the AirTAC SAIL and BSAI cylinder series. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ32BX105-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjusting screw acts as a mechanical stopper that allows you to shorten the effective stroke from its nominal 105 mm down to as little as 75 mm. It only sets the travel end and does not lock the load without live air pressure.
