About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-75
The AirTAC SAIJ32X225-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 225 mm stroke that can be dialed back by up to 75 mm, creating a precise 150-225 mm usable travel window for on-the-fly positioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty tasks requiring exact end-stop tuning.
This variant uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It features PT tapered port threads (G1/8) and operates without a magnet. The extruded aluminum barrel includes sensor grooves on both sides, allowing easy addition of CMSE reed or DMSE electronic switches if position sensing is later required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-75 Is Used
Product Changeovers
Dial in the 150-225 mm travel window during format size changes on packaging lines without physically replacing the cylinder.
Machine Setup
Fine-tune the retract end-position precisely at commissioning to avoid mechanical crashes and optimize cycle timing.
Variable End Stops
Use the 75 mm rear adjuster to create custom stroke lengths on the fly for light-duty testing and assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-75 the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa with highly variable end positions; step up to the 40 mm bore if your application requires 628 N. The 75 mm adjustment window is ideal for product changeovers, letting you fine-tune the retract distance at commissioning without adding external stops or swapping a fixed-stroke SAI cylinder. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air—if load holding is required upon pressure loss, consider an SAIL or BSAI cylinder.
For an exact ISO 15552 replacement, match the 32 mm bore, 225 mm nominal stroke, 75 mm adjustment range, PT port thread, and the specific mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 225 mm stroke is relatively long for a 32 mm rod, external guidance is recommended to prevent excessive side loading and premature seal wear.
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 SAIJ32AX225-75 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the 225 mm nominal length, providing a usable travel window of 150-225 mm. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
