About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-30
The AirTAC SAIJ32X850-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 850 mm travel by up to 30 mm. This yields a usable end-position window of 820-850 mm, making it ideal for fine-tuning machinery setup without swapping components. It delivers 402 N of push force at 0.5 MPa and features a SUS304 stainless steel rod for superior corrosion resistance.
Unlike fixed-stroke SAI units, this model uses an external rear stopper to set the retract distance. The adjuster acts purely as a travel stop and does not hold the load without live air pressure. The extruded aluminum barrel includes dual sensor grooves, and because no magnet is specified, it requires a separate -S variant to utilize CMSE reed or DMSE electronic switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-30 Is Used
Machine Setup Tuning
Dial in the exact 820-850 mm end position during commissioning to perfect product spacing without adding external stopper blocks.
Product Changeover
Quickly adjust the retract stop to accommodate different package lengths on a packaging line, minimizing downtime between runs.
Precision End-Positioning
Use the 30 mm adjustment window to compensate for mechanical wear or slight variations in upstream feeding distances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-30 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa and a highly specific extended travel distance. If you need less force, drop to a smaller bore, or step up to a 40 mm bore for 628 N. The adjustable stroke is perfect for product changeovers, letting you fine-tune the 820-850 mm travel window on the fly instead of machining custom external stops.
This cylinder is dimensionally interchangeable per ISO 15552, using a PT tapered port thread. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the stroke is 850 mm, the 12 mm rod is highly susceptible to side-loading; always use an external guide to prevent rod binding and premature seal wear.
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 SAIJ32BX850-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw lets you shorten the effective stroke from 850 mm down to 820 mm. This stopper only sets the travel end and does not lock or hold the load without continuous air pressure.
