About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX40-20
The AirTAC SAIJ32X40-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 20-40 mm from its 40 mm nominal stroke. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod for enhanced durability against lateral stress. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This adjustable model uses a PT tapered port thread and omits the FB, CA, CB, and CR mounting accessories, utilizing a focused set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. The rear stopper mechanism lets you dial in the exact retract position during commissioning without adding external physical stops or swapping out the entire cylinder.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX40-20 Is Used
Machine Changeovers
Dial in the 20-40 mm retract position precisely during product size transitions without disassembling the pneumatic setup.
End-Stop Calibration
Use the rear adjuster to set exact end-of-stroke limits for delicate positioning tasks on automated workstations.
Variable Product Routing
Adjust the travel window on the fly to accommodate different package dimensions moving down a packaging line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX40-20 the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning on the fly, such as adapting to slightly varying product sizes on a conveyor. If your process needs higher clamping power, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Conversely, lighter duties can often be handled by smaller variants.
Because the rear adjuster acts strictly as a travel stop and the air cushion only manages deceleration, neither component can hold a load in place without continuous live air pressure. For true fail-safe load holding, consider the SAIL series with an air-released lock or the BSAI clamp-lock variant. To match this ISO 15552 interchangeable cylinder exactly, specify the 32 mm bore, 40 mm stroke, 20 mm adjustment, PT port thread, and no magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ 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 SAIJ32AX40-20 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder produces 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster screw lets you shorten the 40 mm nominal stroke by up to 20 mm, creating a 20-40 mm usable travel window. This allows precise end-position tuning at commissioning without external stops.
