About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-100S
The AirTAC SAIJ32X325-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. By turning the integrated stopper screw, you can trim the effective travel back by up to 100 mm, creating a usable movement window of 225 to 325 mm for this specific 325 mm stroke unit. This allows precise end-position tuning during commissioning without swapping out the cylinder or adding external stops.
Delivering 402 N of push force and 345 N of pull force at 0.5 MPa, this 32 mm bore model is equipped with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, and because this unit includes a magnet (-S), it supports position detection using AirTAC CMSE reed or DMSE electronic solid-state switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-100S Is Used
Product Changeover
Dial in the exact end-stop position for different package lengths on a packaging line using the 225-325 mm adjustable travel window.
Machine Setup
Fine-tune the retract position during initial commissioning without fabricating or bolting on external mechanical stoppers.
Variable End Stops
Adjust the stroke dynamically on testing fixtures where the contact point needs to shift based on the specific component being validated.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-100S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires fine-tuning of the retract end-position to accommodate varying product sizes or machine setups. If your process requires less force, stepping down is not an option below 32 mm in this series, but if you need significantly higher thrust, the 40 mm bore provides 628 N push force at 0.5 MPa. The rear adjuster acts purely as a mechanical travel stop and does not hold the load without live air pressure; for true load-holding without continuous air, consider the SAIL pneumatic lock or BSAI clamp-lock series.
Because the 325 mm stroke exceeds 300 mm, the 12 mm diameter rod and M10x1.25 rod thread will experience greater leverage forces if subjected to side loads. An external guide rail is strongly recommended to prevent premature seal wear and rod bending. When replacing an ISO 15552 cylinder, match the 32 mm bore, 325 mm stroke, 100 mm adjustment range, PT tapered port threads, and the -S magnet requirement.
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 SAIJ32AX325-100S 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 0.7 MPa, the push force increases to 563 N.
The rear adjusting screw allows you to shorten the nominal 325 mm stroke by up to 100 mm, providing an effective travel range of 225 to 325 mm. The adjuster is a mechanical stop that sets the end position and does not function as a lock or brake.
