About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-100
The AirTAC SAIJ32X140-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 140 mm stroke that can be mechanically dialed back by up to 100 mm, yielding a highly versatile 40 to 140 mm usable travel window for rapid product changeovers. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod and PT tapered ports.
Because the rear adjuster acts strictly as a mechanical stop to set the retract end position, it cannot hold a load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series. This 32 mm bore model omits the FB, CA, CB, and CR mounts, utilizing a focused ISO 15552 mounting set comprising Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-100 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 40 and 140 mm during commissioning to fine-tune pick-and-place movements without adding external physical stops.
Product Size Changeover
Quickly adapt a packaging line to different carton heights by turning the rear adjuster screw, eliminating the downtime needed to swap out entire cylinders.
Machine Setup Flexibility
Use the wide adjustment range to find the optimal mechanical end position during initial machine build, absorbing design tolerances easily on the factory floor.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-100 the Right Cylinder?
Choose this SAIJ32X140-100 when an application demands extreme stroke variance within a compact footprint, as the 100 mm adjustment range allows a single cylinder to serve multiple product sizes without physical replacement. If you need higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Conversely, if a fixed end position is guaranteed and never requires tuning, a standard SAI cylinder provides a simpler setup.
This SKU includes a SUS304 stainless steel rod for superior corrosion resistance and PT tapered port threads. Since the stroke is 140 mm, side-loading risks are moderate, but an external guide rail is still recommended if the load is heavy or asymmetric. This unit lacks a magnet (-S), so position sensing via CMSE or DMSE switches is not supported without a variant change.
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 SAIJ32BX140-100 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 the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 140 mm nominal stroke by up to 100 mm. This creates a usable travel window of 40 to 140 mm, but it only sets the end position and does not lock or hold the load without continuous air pressure.
