About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-50S
The AirTAC SAIJ32X75-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 25 to 75 mm, allowing you to dial back the 75 mm nominal stroke by up to 50 mm during machine commissioning without adding external stops. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This SKU is built with a SUS420J2 stainless steel rod for improved corrosion resistance and includes a magnet for position sensing. It accepts CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and the PT tapered port threads match the standard G1/8 air connection for this bore size.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-50S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 25 and 75 mm on the fly for packaging machines that process varying carton sizes.
Machine Setup & Changeover
Fine-tune the end position at commissioning without physically swapping cylinders or fabricating external mechanical stops.
Light-Duty Clamping
Provides 402 N of clamping force at 0.5 MPa, with a rear stop screw to precisely set the crush depth.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-50S the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires fine end-position tuning at commissioning or frequent product-size changeovers, replacing the need to swap a fixed-stroke SAI cylinder. If your application demands higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider an external rod lock or the AirTAC SAIL or BSAI series.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 32 mm bore, 75 mm nominal stroke, 50 mm adjustment range, PT G1/8 port, and the -S magnet option. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR mounts.

- ✓ 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 SAIJ32AX75-50S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 75 mm nominal stroke down to a 25 mm minimum. It creates a 25 to 75 mm adjustable window for precise end-position tuning.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
