About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-100
The AirTAC SAIJ32X300-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 300 mm travel by up to 100 mm. This creates a highly flexible 200-300 mm usable stroke window, letting you fine-tune end positions at commissioning without swapping hardware. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This specific configuration features an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The barrel is an extruded aluminum profile with sensor grooves on both sides. Because the 300 mm stroke is relatively long for this compact bore, an external guide is recommended to prevent excessive side-loading on the rod thread.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-100 Is Used
Machine Changeover
Quickly shift the end position by up to 100 mm when adapting the line to a new product size, avoiding physical cylinder replacement.
Variable End-Stop Setup
Dial in the exact 200-300 mm retraction point during commissioning to perfect tooling alignment without adding external mechanical stops.
Light Assembly Positioning
Provides accurate 402 N positioning for compact assembly stations, with the SUS420J2 stainless rod offering resistance to minor environmental moisture.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-100 the Right Cylinder?
Choose this 32 mm bore when your application requires up to 402 N of push force at 0.5 MPa; stepping up to a 40 mm bore would provide 628 N if your load demands more room. The adjustable stroke is ideal for product-size changeovers on a line, replacing the need to bolt on external stops. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It uses PT tapered port threads and operates without a magnet.
Remember that the rear adjuster acts strictly as a travel stop, not a lock, and cannot hold a load without live air pressure. If your setup requires true load-holding without continuous air, consider the SAIL or BSAI series instead. For position sensing, adding an -S magnet variant allows the use of AirTAC CMSE reed or DMSE electronic solid-state switches in the side grooves.

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 SAIJ32AX300-100 FAQ
The rear adjuster screw lets you trim the effective stroke back by up to 100 mm from the 300 mm nominal length, giving a usable travel window of 200-300 mm. The adjuster functions as a mechanical stop to set the end position and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the 32 mm bore provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
