About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-40S
The AirTAC SAIJ32X100-40-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you dial back the 100 mm nominal travel to a 60-100 mm usable window. It delivers 402 N of push force at 0.5 MPa and 724 N at 0.9 MPa. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE solid-state switches.
This variant uses a SUS304 stainless steel rod for corrosion resistance and features a PT tapered port thread. The rear stopper allows fine end-position tuning during commissioning without adding external stops. The adjuster acts purely as a travel stop, not a load lock, so live air is required to hold position.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-40S Is Used
Machine Commissioning
Fine-tune the 60-100 mm travel window during setup to hit exact end positions without swapping cylinders.
Product Changeover
Quickly adjust the retract stop on a packaging line when handling slightly different package lengths.
Variable End Stops
Use the 40 mm rear adjuster to set precise stopping points for light-duty assembly tasks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-40S the Right Cylinder?
Choose this 32 mm bore when your application needs up to 724 N of force and a variable end-stop between 60 and 100 mm. If your setup requires less force, dropping to a 20 mm bore lowers the 0.5 MPa push force to 314 N, whereas stepping up to a 40 mm bore increases it to 628 N. The 100 mm stroke is well within the 1000 mm standard maximum, and the 12 mm rod handles moderate side loads, though long unsupported travel still needs an external guide.
When matching an ISO 15552 replacement, verify the 100 mm stroke, 40 mm adjustment range, PT port thread, and the -S magnet. For load-holding without live air pressure, select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the rear adjuster.
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 SAIJ32BX100-40S FAQ
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 100 mm nominal stroke down to a 60 mm minimum. It is a travel stop, not a lock, so live air is needed to hold the load.
