About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-30
The AirTAC SAIJ32X800-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 770 to 800 mm usable travel window, letting you dial back the retract position by up to 30 mm during commissioning. It delivers 402 N of push force at 0.5 MPa and uses a SUS420J2 stainless steel rod for improved corrosion resistance.
This model features a PT tapered G1/8 port and a 12 mm rod with an M10x1.25 thread. The rear adjuster functions strictly as a travel stop to fine-tune end positions, not as a load lock. For position holding without live air pressure, consider an external pilot-operated check valve or the SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-30 Is Used
Machine Changeover
Fine-tune the 770-800 mm retract stop during product size changes without physically swapping the cylinder or adding external stopper blocks.
Variable End-Stop Positioning
Dial in the exact end-of-stroke position on a long-travel conveyor diverter to accommodate varying package lengths on the fly.
Assembly Calibration
Adjust the retract distance precisely during machine setup to perfect the pressing depth or alignment of long-travel components.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-30 the Right Cylinder?
Choose this 32 mm bore when you need precise retract tuning on a long 800 mm stroke without adding external stops. If your application requires greater thrust, step up to the 40 mm bore which provides 628 N of push force at 0.5 MPa. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
Because this cylinder uses an 800 mm stroke, the 12 mm rod requires an external guide to prevent excessive side-loading and premature seal wear. This SKU is dimensionally interchangeable per ISO 15552, uses a PT port thread, and ships without a magnet (-S not specified). If you need position feedback, select a -S model to use with CMSE reed or DMSE electronic 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 SAIJ32AX800-30 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 800 mm nominal stroke by up to 30 mm, providing a 770 to 800 mm usable travel window. It is a travel stop, not a lock, and will not hold the load without live air pressure.
