About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-40S
The AirTAC SAIJ32X175-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 135 to 175 mm, allowing you to dial back the nominal 175 mm stroke by up to 40 mm during commissioning. In the compact 32 mm bore class, it delivers 402 N of push force at 0.5 MPa and 724 N at 0.9 MPa.
This variant includes a magnet for CMSE or DMSE sensors and uses a SUS304 stainless steel rod for corrosion resistance. It features PT tapered port threads (G1/8) and adjustable air cushions at both ends. The rear stopper sets the retract end position but does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-40S Is Used
Machine Setup & Changeover
Fine-tune the 135-175 mm travel window during product changeovers to set exact retract positions without adding external mechanical stops.
Variable End-Stop Positioning
Dial in the exact end-of-stroke point during commissioning to accommodate material thickness variations on the fly.
Testing & Validation Fixtures
Easily adjust the travel distance for different test sample sizes, leveraging the 402 N push force and SUS304 rod for clean environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-40S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when you need precise end-position tuning without swapping components. If your application requires more force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. For load-holding without continuous air pressure, this cylinder is insufficient since the adjuster is a stop, not a lock; consider the SAIL or BSAI series instead.
To match this ISO 15552 interchangeable cylinder, specify a 32 mm bore, 175 mm stroke, 40 mm adjustment, PT port threads, SUS304 rod material, and a magnet for position sensing. With a 175 mm stroke, the 12 mm rod handles moderate side loads, but an external guide is recommended for heavy lateral forces. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

- ✓ 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 SAIJ32BX175-40S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 40 mm, creating a usable travel window of 135 to 175 mm. This allows precise end-position tuning at commissioning without changing the cylinder.
At 0.5 MPa, it provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
