About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-100
The AirTAC SAIJ32X240-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 140-240 mm usable travel window, allowing you to dial back the 240 mm nominal stroke by up to 100 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty tasks requiring exact end-position tuning without external stops.
This variant is equipped with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible CMSE or DMSE switch mounting. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1 and TCM2, omitting the FB, CA, CB and CR options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-100 Is Used
Machine Changeover
Dial in the exact 140-240 mm travel window during product size changes without swapping hardware or adding external stops.
Variable End Stops
Set precise retract positions for multi-format assembly lines, using the 100 mm adjustment range to adapt the stroke on the fly.
Light-Duty Positioning
Leverage the 402 N push force and SUS304 rod for repeatable, corrosion-resistant actuation in clean or washdown environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-100 the Right Cylinder?
Select this 32 mm bore cylinder when an application demands a highly variable end-stop within a 140-240 mm range, delivering 402 N push force at 0.5 MPa. If your process requires less force and a shorter base stroke, stepping down is viable, but for heavier loads, a 40 mm bore provides 628 N. The rear adjuster acts purely as a mechanical stop for deceleration and positioning, not a lock; it will not hold the load without live air pressure. For true fail-safe holding, consider the SAIL or BSAI series.
Because the nominal stroke is 240 mm, the 12 mm rod and M10x1.25 thread should be guided to prevent excessive side-loading on long unsupported travels. This SKU is dimensionally interchangeable per ISO 15552 mounting interfaces, configured with PT ports, no magnet, and the SUS304 rod option.

- ✓ 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 SAIJ32BX240-100 FAQ
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. The 32 mm bore supports a standard operating speed range of 30-800 mm/s.
The rear adjuster screw lets you shorten the effective travel from the 240 mm nominal stroke down to 140 mm. It functions as a mechanical stop to fine-tune the retract position at commissioning, but it is not a lock and requires live air to hold the load.
