About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-10
The AirTAC SAIJ32X300-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 300 mm travel by up to 10 mm. This yields a precise 290-300 mm usable window for fine-tuning the retract end position at commissioning without swapping the unit. It delivers a 402 N push force at 0.5 MPa, fitting compact automation tasks.
Built with a SUS304 stainless steel rod and a PT tapered port, this 32 mm bore model runs at speeds of 30-800 mm/s. The rear adjuster acts purely as a travel stop to set deceleration; it does not lock the load. For position holding without live air, you would need an external rod lock or a related type like the SAIL. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-10 Is Used
Machine Changeover
Dial in the 290-300 mm retract position during product size changes without physically swapping the cylinder or adding external stop blocks.
End-Stop Tuning
Perfect the final deceleration point at commissioning using the rear screw, ensuring delicate parts are not crushed at the end of travel.
Variable Positioning
Adjust the travel window on packaging lines to handle slightly different carton lengths while maintaining standard ISO 15552 mounting.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-10 the Right Cylinder?
Choose this 32 mm bore when your application needs 402 N of push force at 0.5 MPa. If you require less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N. The adjustable stroke is ideal for product changeovers on a line where the exact end-stop varies slightly, saving you from installing external stops. To replace this with an ISO 15552 equivalent, match the 32 mm bore, 300 mm stroke, 10 mm adjustment, PT port, and your chosen mounting.
Because the stroke is 300 mm, the 12 mm rod and M10x1.25 thread need careful alignment. Long unsupported strokes increase side-load risk, so an external guide is recommended to prevent premature 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 SAIJ32BX300-10 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 the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a 290-300 mm travel window. It functions as a mechanical stop to tune the end position and does not hold the load without live air pressure.
