About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-75
The AirTAC SAIJ32X240-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 165 to 240 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads.
This adjustable-stroke design allows you to fine-tune the retract end position at commissioning without external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-75 Is Used
Machine Setup & Changeover
Dial in the exact retract position within the 165-240 mm window during product line changeovers without swapping cylinders.
Variable End-Stop Positioning
Use the rear adjusting screw to fine-tune the end-of-stroke stop for precise manufacturing tasks requiring 402 N of force.
Light Conveyor Sorting
Actuate sorting gates on conveyor lines where the SUS304 stainless steel rod provides necessary washdown corrosion resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-75 the Right Cylinder?
Choose this 32 mm bore model when an application requires 402 N of push force at 0.5 MPa and a variable end-stop. If your process demands less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N. The 75 mm adjustment range is perfect for product-size changeovers on a line. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For load-holding without pressure, consider the SAIL or BSAI series.
Because the 240 mm stroke exceeds 300 mm? No, but even at 240 mm, the 12 mm rod diameter and M10x1.25 thread handle moderate side loads. For long unsupported strokes, always use an external guide. This SAIJ model supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set, omitting FB, CA, CB, and CR.
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 SAIJ32BX240-75 FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 75 mm, providing a usable travel window of 165 to 240 mm. The adjuster acts as a mechanical stop and does not lock the load without live air pressure.
At 0.5 MPa, it provides 402 N of push force and 345 N of pull force. The operating speed ranges from 30 to 800 mm/s, and it uses a G1/8 port.
