About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-40S
The AirTAC SAIJ32X375-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 335 to 375 mm. Delivering 402 N of push force at 0.5 MPa, it utilizes a SUS304 stainless steel rod (code B) for superior corrosion resistance. The integrated magnet (-S) enables precise position detection using AirTAC CMSE reed or DMSE electronic sensors.
This adjustable-stroke variant allows you to fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops. It features PT tapered port threads and a 12 mm rod with an M10x1.25 thread. Remember that the rear adjuster acts as a travel stop, not a lock; it cannot hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-40S Is Used
Machine Changeover
Dial in the exact retract distance within the 335-375 mm window when switching between product sizes on a packaging line.
Sensor Positioning
Leverage the built-in magnet with DMSE electronic sensors to confirm the adjusted end-stop on automated assembly equipment.
Corrosive Setup
Rely on the SUS304 stainless steel rod for fine-tuning end positions in food or chemical processing environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-40S the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires exact end-position tuning within a 335-375 mm window, stepping down from a 40 mm bore (which offers 628 N push at 0.5 MPa) if your force needs are lower. The adjustable stroke is ideal for machine setup and product changeovers, whereas a fixed SAI cylinder locks you into one dimension. For load-holding without live pressure, consider the SAIL or BSAI series instead.
As an ISO 15552 interchangeable cylinder, replacement requires matching the 32 mm bore, 375 mm stroke, 40 mm adjustment, PT threads, and the -S magnet. Because the stroke is 375 mm, the 12 mm rod may experience side-load deflection over this long unsupported distance; always use an external guide to prevent premature wear.
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 SAIJ32BX375-40S 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 pressure of 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster screw lets you shorten the nominal 375 mm stroke by up to 40 mm, creating a usable travel window of 335 to 375 mm. The adjuster acts as a mechanical stop to fine-tune the end position without changing the cylinder itself.
