About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX225-75S
The AirTAC SAIJ32X225-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 150 to 225 mm usable travel window, allowing you to dial back the 225 mm nominal stroke by up to 75 mm during commissioning without adding external stops. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks.
This variant uses a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides. It operates at 30-800 mm/s with a G1/8 port and 27 mm cushions at both ends.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX225-75S Is Used
Product Changeover Tuning
Dial in the exact end-stop for varying package sizes on a packaging line without swapping out the entire actuator.
Machine Setup Calibration
Fine-tune the 150-225 mm travel window during initial commissioning to perfect sensor triggering and end-of-stroke positioning.
Light-Duty Positioning
Leverage the 402 N push force and SUS304 rod for precise, corrosion-resistant component placement in automated assembly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX225-75S the Right Cylinder?
Choose this 32 mm bore when a 402 N push force is sufficient, or step up to the 40 mm bore for 628 N if your load demands more clamping power. The adjustable rear stopper is ideal for product changeovers, letting you fine-tune the end position quickly versus a fixed-stroke SAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
The rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider an external rod lock or the SAIL series. Because the 225 mm stroke exceeds 300 mm only marginally, side-load risks are moderate, but an external guide is still recommended for heavy lateral loads.
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 SAIJ32BX225-75S 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 delivers up to 82 kgf.
The rear adjuster screw allows you to shorten the 225 mm nominal stroke by up to 75 mm, creating a usable travel window of 150 to 225 mm. This stopper only sets the end position and does not lock the load without continuous air pressure.
