About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-10
The AirTAC SAIJ32X375-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 375mm travel that can be fine-tuned down by 10mm, yielding a usable 365-375mm end-position window. Delivering 402N of push force at 0.5MPa, it integrates a 12mm carbon steel rod and M10x1.25 threading to handle moderate loads.
This unit is configured with a SUS420J2 stainless steel rod (option A) for superior corrosion resistance in humid environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Because the 375mm stroke is relatively long for the 32mm bore, an external guide is recommended to prevent excessive side-loading on the rod.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-10 Is Used
Machine Setup Tuning
Dial in the exact 365-375mm travel window during initial machine commissioning to perfectly align end-of-stroke tooling without machining external stoppers.
Product Size Changeover
Quickly trim the 10mm stroke adjustment on packaging lines when handling slightly shorter product lengths, ensuring precise positioning.
Assembly Station Calibration
Fine-tune the end-stop on automated assembly presses to accommodate varying component tolerances without replacing the entire actuator.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-10 the Right Cylinder?
Choose this 32mm bore adjustable-stroke cylinder when your application requires precise end-position tuning during commissioning or product changeover without swapping out the physical cylinder. If you need higher force, stepping up to the 50mm bore yields 982N at 0.5MPa. Unlike a fixed-stroke SAI, the SAIJ rear screw allows you to dial in the exact 365-375mm travel window on the fly.
The rear adjuster acts purely as a travel stop and works alongside the 27mm air cushions to decelerate the piston; neither will hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series. This configuration features PT tapered G1/8 ports and omits the FB, CA, CB, and CR mounting options, utilizing the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

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 SAIJ32AX375-10 FAQ
The rear adjusting screw allows you to shorten the nominal 375mm stroke by up to 10mm, providing a usable travel window of 365-375mm. This stopper sets the retract end position but does not lock the load without live air pressure.
At 0.5MPa operating pressure, the SAIJ32X375-10 provides 402N of push force and 345N of pull force. It can deliver up to 724N of push force at 0.9MPa.
