About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-30
The AirTAC SAIJ32X240-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 210 to 240 mm usable travel window, allowing you to dial in the exact end position during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds of 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is non-magnetic and cannot host position switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-30 Is Used
End-Stop Calibration
Dial in the exact 210-240 mm retract position during machine setup without fabricating custom external stopper blocks.
Product Changeover
Quickly adjust the travel end for different package sizes on a packaging line, using the rear screw to trim up to 30 mm.
Light-Load Positioning
Move light components with 402 N of thrust while relying on the fine adjustment to perfect the final placement.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-30 the Right Cylinder?
Choose this 32 mm bore when you need 402 N of thrust at 0.5 MPa and a 240 mm stroke that can be trimmed by up to 30 mm. If your application requires higher force, stepping up to the 40 mm bore yields 628 N of push force. The rear adjuster screw acts strictly as a travel stop to fine-tune the retract position; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.
Because the 240 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 thread may experience side-loading forces. An external guide is recommended to prevent premature seal wear. This cylinder uses a PT tapered port thread and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32BX240-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum allowable pressure is 1.0 MPa.
A rear adjuster screw lets you shorten the nominal 240 mm stroke by up to 30 mm, creating a 210-240 mm usable travel window. This stopper only sets the end position and does not lock the load without continuous air pressure.
