About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-100S
The AirTAC SAIJ32X325-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear mechanical adjuster. It provides a nominal 325 mm stroke that can be dialed back by up to 100 mm, creating a precise 225-325 mm usable travel window for highly flexible machine setups. Delivering 402 N of push force at 0.5 MPa, it handles lighter positioning tasks with ease.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and an integrated magnet (-S) for position sensing. The extruded aluminum barrel houses sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. It uses a PT G1/8 port and relies on adjustable air cushions at both ends to decelerate the moving load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-100S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 225 and 325 mm during commissioning to accommodate different material lengths without mechanical rebuilds.
Product Size Changeovers
Quickly adjust the stroke window on packaging lines to handle varying carton sizes, leveraging the 100 mm trim range to maintain precise stopping points.
Light-Duty Sensing Tasks
Utilize the integrated magnet with DMSE electronic sensors to confirm end positions in compact assembly machinery while benefiting from the corrosion-resistant SUS304 rod.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-100S the Right Cylinder?
Choose this 32 mm bore when your application requires up to 402 N of push force at 0.5 MPa alongside a highly variable end-stop. If your setup demands greater thrust, stepping up to the 40 mm bore yields 628 N. The 100 mm adjustment range is perfect for product-size changeovers, allowing you to fine-tune the retract position without swapping cylinders or adding external stops. Because the 325 mm stroke is relatively long for this compact bore, ensure adequate external guiding to prevent excessive side-loading on the rod.
This SKU is dimensionally interchangeable per ISO 15552. To match this configuration exactly, specify the 32 mm bore, 325 mm stroke, 100 mm adjustment, PT G1/8 port, and the -S magnet. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider an AirTAC SAIL or BSAI cylinder. Available mountings include Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ32BX325-100S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At a maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm, creating a usable travel window of 225 to 325 mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without continuous air pressure.
