About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-75
The AirTAC SAIJ32X175-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 100 to 175 mm, allowing you to dial back the nominal stroke by up to 75 mm during commissioning or product changeovers. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for corrosion resistance and features PT tapered port threads.
The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. Unlike a fixed-stroke SAI cylinder, this model lets you fine-tune the retract end-position without adding external stops. The rear adjuster acts purely as a mechanical stop to set the travel endpoint, not as a lock, so it cannot hold a load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-75 Is Used
Machine Setup Calibration
Dial in the exact retract end-position during initial commissioning without swapping cylinders or adding external stopper blocks.
Product Changeover
Quickly adjust the travel window from 100 to 175 mm to accommodate varying product sizes on the same production line.
End-Stop Trimming
Use the 75 mm rear adjustment screw to fine-tune the stroke distance and prevent mechanical interference at the end of travel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-75 the Right Cylinder?
Choose this 32 mm bore when you need precise end-stop tuning within a 100-175 mm travel window. If your application requires higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The SUS304 rod material is ideal for environments where corrosion resistance is a priority. Because the stroke is 175 mm, side loading is minimal, but always ensure proper load guidance for long unsupported travels.
This cylinder is dimensionally interchangeable per ISO 15552 standards. For exact replacement matching, verify the 32 mm bore, 175 mm nominal stroke, 75 mm adjustment range, PT port threads, and double-acting single-rod configuration. Note that this model does not include a magnet for sensors. If load holding is required without continuous air pressure, consider the SAIL or BSAI series instead of relying on the rear stopper.
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 SAIJ32BX175-75 FAQ
It features a rear adjuster screw that lets you shorten the effective stroke by up to 75 mm, providing a usable travel window of 100 to 175 mm. The adjuster acts as a mechanical stop to set the end position and does not lock or hold the load without live air pressure.
At 0.5 MPa operating pressure, the 32 mm bore provides 402 N of push force and 345 N of pull force. It can achieve up to 724 N of push force at 0.9 MPa.
