About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-40
The AirTAC SAIJ32X50-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 50mm stroke with an adjustment range of 40mm, yielding a highly versatile 10-50mm usable travel window for precise retract positioning. The 32mm bore generates 402N of push force at 0.5 MPa, making it suited for lighter-duty tasks.
This variant uses a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance compared to standard carbon steel. It features PT tapered port threads (G1/8) and lacks a magnet, meaning it cannot host CMSE or DMSE sensors. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-40 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance from 10 to 50mm during machine setup, allowing rapid accommodation of varying product sizes on a shared line.
Light-Duty Positioning
Leverage the 402N push force at 0.5 MPa for precise, low-impact positioning of small components without needing complex external stopper blocks.
Corrosive Environment Actuation
Utilize the SUS420J2 stainless steel rod option in light industrial or lab settings where standard carbon steel rods might face moisture or chemical exposure.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-40 the Right Cylinder?
Choose this 32mm bore cylinder when an application requires fine-tuning the end-of-stroke position during commissioning or product changeovers without swapping out the entire body or adding external stops. If your setup needs slightly higher force, stepping up to a 40mm bore yields 628N of push force at 0.5 MPa. Conversely, for even smaller footprint requirements, you would drop down to a smaller standard size.
Because the stroke is under 300mm, side-loading is less critical, but the 12mm rod still requires external guidance for heavy lateral loads. Remember that the rear adjuster only sets the travel end; it is not a locking mechanism. For true fail-safe load holding without continuous air pressure, consider the SAIL series or an external rod lock. This SAIJ model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts.
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 SAIJ32AX50-40 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum pressure of 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster screw lets you shorten the effective stroke by up to 40mm from the nominal 50mm. This creates a usable travel window of 10 to 50mm, allowing you to fine-tune the retract end position during commissioning without changing the cylinder itself.
