About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-40
The AirTAC SAIJ32X225-40 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 185-225 mm, allowing you to dial back the 225 mm nominal stroke by up to 40 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant features a SUS420J2 stainless steel piston rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the reduced SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-40 Is Used
Machine Setup Tuning
Fine-tune the 185-225 mm travel window during initial commissioning to dial in exact end positions without swapping cylinders.
Product Changeover
Quickly adjust the retract end-stop on packaging lines when handling slightly different carton or product sizes.
Light Assembly Positioning
Apply the 402 N push force for precise, lighter-duty placement and pressing tasks within the adjustable travel range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-40 the Right Cylinder?
Choose this 32 mm bore when 402 N of thrust at 0.5 MPa is sufficient, stepping up to the 40 mm bore (628 N) if your payload increases. The adjustable stroke is selected over a fixed SAI when you need variable end-stops for product changeovers without adding external stops. Note that the rear adjuster is a travel stop, not a lock; for load-holding without live air, consider SAIL or BSAI. As an ISO 15552 interchangeable cylinder, match your replacement by bore, stroke, 40 mm adjustment, PT port, and mounting.
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 SAIJ32AX225-40 FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective travel from 225 mm down to 185 mm. It only sets the end position and does not hold the load without live air pressure.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. It operates at speeds between 30-800 mm/s.
