About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX70-10
The AirTAC SAIJ32X70-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the effective travel down to a 60-70 mm window. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread.
Unlike a fixed-stroke SAI cylinder, this model lets you dial in the retract end-position at commissioning without adding external stops. The rear adjuster acts purely as a mechanical travel stop to set deceleration, meaning it will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX70-10 Is Used
Machine Setup & Commissioning
Dial in the exact 60-70 mm travel window during initial machine build without swapping cylinders or fabricating external stopper blocks.
Product Size Changeover
Quickly adjust the retract end-position by up to 10 mm on packaging lines handling varying product lengths.
Fine-Positioning Tasks
Provides 402 N of thrust at 0.5 MPa for light-duty assembly stations where the rear mechanical stop fine-tunes the final approach distance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX70-10 the Right Cylinder?
Choose this 32 mm bore when you need 402 N of push force at 0.5 MPa (or 724 N at 0.9 MPa) with precise end-stop tuning. If your application requires less force, stepping down to a 25 mm bore offers lighter dynamics, while stepping up to a 40 mm bore provides 628 N at 0.5 MPa for higher load demands. The adjustable 10 mm window is ideal for product changeovers where exact end-positioning matters.
For an exact ISO 15552 replacement match, verify the 32 mm bore, 70 mm nominal stroke, PT port thread, SUS304 (B) rod material, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is under 300 mm, side-load stress is minimal, but always ensure standard guiding for optimal rod life.
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 SAIJ32BX70-10 FAQ
The rear adjuster screw allows you to shorten the nominal 70 mm stroke by up to 10 mm, creating a usable travel window of 60-70 mm. This mechanical stopper sets the end-position and deceleration point without requiring a cylinder swap.
At 0.5 MPa operating pressure, the SAIJ32X70-10 provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
