About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-75S
The AirTAC SAIJ32X175-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the 175 mm nominal stroke by up to 75 mm, creating a highly flexible 100-175 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it uses a robust SUS420J2 stainless steel rod and includes a magnet for CMSE reed and DMSE electronic sensors.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops during machine commissioning or product changeovers. The rear screw acts purely as a travel stop to set the retract end position, meaning it will not hold a load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-75S Is Used
Machine Commissioning
Fine-tune the retract end position during initial setup without machining external stopper blocks or changing the cylinder.
Product Changeover
Quickly adjust the 100-175 mm travel window on a packaging line to accommodate different product sizes.
Variable End Stops
Dial in the exact retract distance for precise positioning tasks that require flexible end-of-stroke control.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-75S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa, but demands variable end-stop positioning within a 100-175 mm window. If your setup requires less force, stepping down is not an option in the standard line, but stepping up to a 40 mm bore yields 628 N. Conversely, if you need higher thrust, the 50 mm bore provides 982 N. The integrated magnet (-S) enables precise position sensing.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 175 mm stroke, 75 mm adjustment range, PT tapered port thread, and SUS420J2 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles. Because the 175 mm stroke approaches the mid-range for this bore, ensure your mounting handles side loads adequately.
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 SAIJ32AX175-75S FAQ
The rear adjuster allows you to shorten the 175 mm nominal stroke by up to 75 mm, providing a usable travel window of 100-175 mm. It acts as a mechanical stop for end-position tuning and does not lock the load without air pressure.
At 0.5 MPa operating pressure, it 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.
