About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-100S
The AirTAC SAIJ32X350-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 32mm bore, a 350mm nominal stroke, and an integrated magnet for position sensing. By turning the rear stopper screw, you can trim the effective travel back by up to 100mm, creating a precise 250-350mm usable stroke window without needing external stops.
This model delivers 402N of push force at 0.5 MPa and uses a G1/8 port. It includes an SUS420J2 stainless steel rod for improved corrosion resistance and pairs with AirTAC CMSE reed or DMSE electronic sensors via its dual-side barrel grooves. The variable air cushions at both ends decelerate the load, but note that the adjuster acts only as a travel stop, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-100S Is Used
Product Size Changeover
Dial in the 250-350mm travel window on the fly to accommodate varying package lengths on a packaging line without swapping out the entire actuator.
Machine Commissioning
Fine-tune the exact end-of-stroke position during initial setup to perfectly align tooling, avoiding the need to machine custom external spacers.
Variable End Stops
Provide adjustable physical stops for diverter gates on a conveyor system, allowing operators to quickly reconfigure sorting distances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-100S the Right Cylinder?
Choose this 32mm bore adjustable cylinder when you need fine end-position tuning during machine commissioning or frequent product size changeovers, rather than installing a fixed-stroke SAI cylinder. If your application requires greater thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. Conversely, if you need less force, the 32mm bore is the smallest standard option in this series.
When replacing an ISO 15552 cylinder, match the 32mm bore, 350mm stroke, 100mm adjustment range, PT tapered port thread, and the -S magnet requirement. Because the 350mm stroke is relatively long for a 32mm rod, it is highly recommended to use an external guide to prevent excessive side-loading. For applications that must hold a load without live air pressure, this cylinder is insufficient; consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32AX350-100S FAQ
It features a rear stopper screw that allows you to shorten the effective stroke by up to 100mm. This provides a usable travel window of 250-350mm, which can be fine-tuned during commissioning without changing the cylinder's physical mounting.
At a standard operating pressure of 0.5 MPa, the SAIJ32X350-100-S generates 402N of push force and 345N of pull force. At its maximum pressure of 1.0 MPa, it can deliver up to 82kgf.
