About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-10
The AirTAC SAIJ32X650-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you dial in the exact end position. It provides a usable travel window of 640-650 mm, enabling fine-tuning without swapping components. With a 32 mm bore, it delivers 402 N of push force at 0.5 MPa and reaches speeds up to 800 mm/s.
This variant features a SUS420J2 stainless steel rod for improved corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though position sensing requires adding a magnet. The rear adjuster acts purely as a travel stop to decelerate the load, meaning it will not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-10 Is Used
Machine Setup Tuning
Dial in the exact 640-650 mm retract position during initial commissioning without adding external shims or physical stops.
Product Changeover
Quickly adjust the stroke end-position by up to 10 mm on packaging lines when handling slightly different carton sizes.
Variable End-Stop Control
Fine-tune the travel limit on testing fixtures where a precise, adjustable mechanical end-stop is required for repeated cycles.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-10 the Right Cylinder?
Choose this 32 mm bore when you need 402 N of thrust at 0.5 MPa and a commissioning adjustment window to compensate for mechanical tolerance. If your application requires higher force, stepping up to the 40 mm bore provides 628 N. The 10 mm adjustment range is ideal for variable end-stops during product changeover. Because the 650 mm stroke is long, an external guide is recommended to prevent excessive side loading on the piston rod. For load-holding without live pressure, consider the SAIL or BSAI series instead of relying on the stopper.
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 SAIJ32AX650-10 FAQ
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. The operating speed ranges from 30-800 mm/s.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 650 mm nominal stroke by up to 10 mm, giving a usable travel window of 640-650 mm. It is a stop, not a lock, and will not hold the load without air pressure.
