About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-100S
The AirTAC SAIJ32X140-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 140mm nominal stroke that can be fine-tuned down by up to 100mm, providing a highly versatile 40-140mm usable travel window for precise end-position calibration.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and an integrated magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions while omitting FB, CA, CB, and CR bracket options in favor of the Basic, FA, LB, TC, FTC, TCM1, and TCM2 set.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-100S Is Used
Variable End-Stop Calibration
Ideal for test fixtures where the exact stopping point of the 12mm rod must be dialed in precisely within the 40-140mm window during commissioning.
Product Size Changeover
Enables rapid line changeovers on packaging equipment by adjusting the rear stopper up to 100mm rather than physically replacing the cylinder.
Corrosive Environment Actuation
The SUS304 stainless steel rod makes this adjustable cylinder suitable for light-duty positioning in environments where standard carbon steel rods would degrade.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-100S the Right Cylinder?
Choose this 32mm bore cylinder when an application demands extreme setup flexibility, as the 100mm adjustment range allows a single unit to cover multiple product sizes without swapping hardware. If your setup requires less than 402N of push force at 0.5 MPa, stepping down is not an option in this series, but stepping up to the 40mm bore yields 628N. Conversely, lighter duties might use a fixed SAI cylinder if rear-tuning is unnecessary.
Because the 140mm stroke is under the 300mm threshold, side-load stress on the 12mm rod is moderate, but an external guide remains recommended for heavy off-center loads. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ32X140-100-S will not hold a load without live air, so consider an AirTAC SAIL or BSAI cylinder if true mechanical locking is required.
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 SAIJ32BX140-100S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 100mm without changing the cylinder. This gives the 140mm nominal stroke a usable travel window of 40-140mm for fine-tuning at commissioning.
