About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-75
The AirTAC SAIJ32X240-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 165-240mm usable travel window, letting you dial back the 240mm nominal stroke by up to 75mm during commissioning. Delivering 402N of push force at 0.5MPa, it suits precise positioning tasks.
This variant uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the internal magnet, meaning electronic DMSE or reed CMSE switches cannot be directly mounted.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-75 Is Used
Variable End-Stop Tuning
Dial in the exact 165 to 240mm stroke during machine setup to accommodate different product sizes without changing hardware.
Changeover Positioning
Quickly adjust the retract end-position on packaging equipment during format changes to minimize downtime.
Commissioning Calibration
Fine-tune the final end-of-stroke position during initial machine commissioning to prevent mechanical crashes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-75 the Right Cylinder?
Choose this 32mm bore when 402N push force at 0.5MPa is sufficient, avoiding the bulk of a 40mm bore that yields 628N. The 75mm adjustment range is ideal for product changeovers on a packaging line, allowing variable end-stops without physically swapping the cylinder or adding external stops.
For any stroke at or above 240mm, long unsupported rod travel increases side-load risks, so an external guide is recommended. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding without pressure, explore an AirTAC SAIL or BSAI cylinder.

- ✓ 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 SAIJ32AX240-75 FAQ
The rear adjuster screw lets you shorten the effective travel from the 240mm nominal stroke down to 165mm, providing a 75mm tuning window without altering the cylinder mount.
It delivers 402N of push force and 345N of pull force at 0.5MPa, scaling up to 724N push force at 0.9MPa.
