About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-20S
The AirTAC SAIJ32X350-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end-position during commissioning. It provides a usable travel window of 330 to 350 mm, letting you trim back up to 20 mm without adding external stops or swapping the actuator. Delivering 402 N of push force and 345 N of pull force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant features a SUS420J2 stainless steel rod for corrosion resistance and includes a magnet (-S) for position sensing with CMSE reed or DMSE electronic switches. The 12 mm rod and M10x1.25 thread handle standard loads, but at a 350 mm stroke, the extended unsupported rod is susceptible to side-loading and requires an external guide. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-20S Is Used
Machine Setup Tuning
Dial in the exact retract position within a 330-350 mm window during initial commissioning without machining external stopper blocks.
Product Size Changeovers
Quickly adjust the end-stop by up to 20 mm to accommodate varying package lengths on a packaging line.
Variable End Positioning
Use the fine-tune adjustment screw to set precise retract limits for light-duty assembly tasks requiring 402 N of push force.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX350-20S the Right Cylinder?
Choose this 32 mm bore when you need precise variable end-stops for product changeovers on a packaging line, delivering 345 N pull force at 0.5 MPa. If your application requires higher thrust, stepping up to the 40 mm bore yields 528 N pull force at 0.5 MPa. Because the 350 mm stroke creates a long extension, an external guide is strongly recommended to prevent side-load damage to the rod seals.
The rear adjuster acts solely as a travel stop to set deceleration and end-position; it is not a lock. The SAIJ32X350-20-S will not hold a load without live air pressure, so for fail-safe load-holding, consider an SAIL (air-released lock) or BSAI (clamp-lock) cylinder. This actuator is dimensionally interchangeable per ISO 15552, featuring PT tapered ports and a -S magnet for CMSE / DMSE sensors.

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 SAIJ32AX350-20S FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw lets you shorten the effective travel from 350 mm down to 330 mm. It functions as a mechanical stop to fine-tune the end position, but it does not lock or hold the load without continuous air pressure.
