About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-75
The AirTAC SAIJ32X230-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 230 mm stroke that can be dialed back by up to 75 mm, creating a precise 155-230 mm usable travel window for exact end-position tuning at commissioning. Built with a SUS304 stainless steel rod and PT tapered ports, it delivers 402 N of push force at 0.5 MPa.
The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract position without adding external stops; it does not lock or hold the load without live air pressure. For position holding without air, consider an external rod lock or the AirTAC SAIL series. This 32 mm bore model includes sensor grooves on both sides and supports a speed range of 30-800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-75 Is Used
Machine Changeover
Dial in the 155-230 mm travel window during product size changes without physically swapping the cylinder or repositioning hard stops.
End-Position Tuning
Fine-tune the retract stroke by up to 75 mm during commissioning to perfectly align tooling without adding external mechanical stops.
Variable Sorting Stops
Adjust the stroke length on the fly for a pneumatic diverter arm handling differently sized packages on a packaging line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-75 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires up to 402 N of push force at 0.5 MPa and variable end-stop positioning. If your setup demands higher thrust, stepping up to the 40 mm bore yields 628 N of push force at the same pressure. The adjustable 155-230 mm window is ideal for product changeovers, whereas a fixed-stroke SAI cylinder is better suited for applications with rigid, unchanging travel requirements.
When replacing an ISO 15552 cylinder, verify the 32 mm bore, 230 mm stroke, PT port thread, and mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Because the 230 mm stroke is relatively long for this compact bore, ensure adequate external guiding to prevent excessive side-loading on the rod.
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 SAIJ32BX230-75 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 75 mm, providing a usable travel window of 155 to 230 mm. The adjuster functions as a mechanical stop for end-position tuning and does not lock the cylinder position without continuous air pressure.
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 of thrust.
