About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-30
The AirTAC SAIJ32X175-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 145-175 mm usable travel window, allowing you to dial back the 175 mm nominal stroke by up to 30 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it fits light-duty positioning tasks perfectly.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning electronic DMSE or reed CMSE switches cannot be used without modification.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-30 Is Used
End-Position Tuning
Dial in the exact 145-175 mm retract distance during machine commissioning to perfect product placement without adding external stops.
Product Changeover
Quickly adjust the stroke by up to 30 mm on a packaging line when switching to different product sizes, minimizing downtime.
Light-Duty Positioning
Leverage the 402 N push force and SUS304 rod for precise, corrosion-resistant component handling in smaller assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-30 the Right Cylinder?
Select this 32 mm bore when an application requires precise end-position tuning without swapping components; it yields 345 N of pull force at 0.5 MPa. If your setup needs greater thrust, stepping up to the 40 mm bore increases push force to 628 N. Conversely, if you need less force, dropping to a smaller bore is advised. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series.
For an exact ISO 15552 replacement match, ensure you specify the 32 mm bore, 175 mm stroke, 30 mm adjustment range, PT port threads, SUS304 (B) rod material, and the correct mounting set. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR options. Since the stroke is under 300 mm, side-load stress on the 12 mm rod is moderate, but external guiding remains 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 SAIJ32BX175-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 175 mm nominal stroke by up to 30 mm, creating a 145-175 mm travel window. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
