About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-10
The AirTAC SAIJ32X850-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 402N of push thrust at 0.5 MPa and provides a usable travel window of 840 to 850 mm. The PT tapered port thread and SUS420J2 stainless steel rod (code A) ensure robust corrosion resistance for demanding environments.
This adjustable-stroke model lets you fine-tune the retract end position at commissioning without adding external stops. The rear adjuster acts purely as a travel stop, not a lock, so live air is required to hold the load. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-10 Is Used
Machine Setup Tuning
Dial in the exact 840 to 850mm retract position during machine commissioning without swapping physical hardware.
Product Changeover
Quickly adjust the end-stop by up to 10mm to accommodate slight length variations when changing product runs on a line.
Long-Travel Assembly
Handle extended reach operations with a 32mm bore that supplies 402N of push force at 0.5 MPa for standard assembly tasks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-10 the Right Cylinder?
Choose this 32mm bore if you need 402N push force at 0.5 MPa with precise end-stop tuning over a long 850mm travel. Stepping up to the 40mm bore increases push force to 628N, while dropping to a smaller bore reduces the footprint. Because the 850mm stroke is long and the 12mm rod is relatively slim, an external guide is recommended to prevent excessive side-load deflection.
An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for product changeovers. For load-holding without continuous air pressure, this cylinder is insufficient; consider the SAIL air-released lock or BSAI clamp-lock instead. This SKU uses PT ports, omits the FB/CA/CB/CR mounting set, and lacks a magnet for sensors.
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 SAIJ32AX850-10 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can deliver up to 724N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the effective stroke by up to 10mm, creating a usable travel window of 840 to 850mm. It is a travel stop, not a lock, so it cannot hold the load without live air pressure.
