About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-40
The AirTAC SAIJ32X240-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 200 mm from its 240 mm nominal length. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This specific SKU ships with a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The rear adjuster acts purely as a mechanical stop to set the end position during commissioning; it does not lock the load without live air pressure. For applications requiring true load-holding, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-40 Is Used
Machine Changeovers
Dial in the exact end position from 200 to 240 mm during product size changes without bolting on external stops or replacing the actuator.
Light Diverter Arms
Provides 402 N of push force at 0.5 MPa to actuate lightweight sorting gates, with the rear screw allowing precise timing adjustments.
End-Stop Tuning
Fine-tune the retract end-position at commissioning to perfectly align tooling, using the adjuster as a stop rather than a load-holding lock.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-40 the Right Cylinder?
Choose this 32 mm bore when your application requires a compact actuator with a maximum 0.5 MPa push force of 402 N. If your process demands greater thrust, stepping up to the 40 mm bore yields 628 N. The 40 mm adjustment range on this model is ideal for product changeovers on a packaging line, allowing operators to dial in the exact end-stop without swapping out the cylinder or adding external stops.
As a dimensionally interchangeable ISO 15552 profile cylinder, it matches standard mounting footprints. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 240 mm stroke exceeds 200 mm, ensure you use an external guide to support the load and minimize side-load wear on the 12 mm rod and M10x1.25 thread.
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 SAIJ32BX240-40 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 40 mm, providing a usable travel window of 200 to 240 mm. This allows precise end-position tuning at commissioning without changing the cylinder.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
