About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-10S
The AirTAC SAIJ32X240-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to dial back the 240 mm nominal travel by up to 10 mm, creating a precise 230-240 mm end-position window for commissioning without external stops. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread for a tight pneumatic seal.
Because this variant includes the -S magnet option, it directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors mounted into the dual-side extruded barrel grooves. The rear adjuster acts purely as a mechanical stop to set the retraction end-point; it does not lock the load, meaning you need live air or an external pilot-operated check valve to hold position.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-10S Is Used
Machine Changeover
Quickly dial in the 230-240 mm travel window during product size changes without swapping cylinders or adding external shims.
End-Stop Tuning
Use the 10 mm rear adjuster to precisely set the retraction end-position during initial commissioning for high-accuracy repeated motions.
Sensor-Driven Handling
Leverage the integrated -S magnet with DMSE electronic sensors to confirm stroke completion in automated assembly pick-and-place units.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-10S the Right Cylinder?
Choose this 32 mm bore when you need 402 N of thrust at 0.5 MPa and on-the-fly end-position tuning; if your application requires higher force, stepping up to the 40 mm bore yields 628 N. The 10 mm adjustment range is ideal for fine-tuning machine changeovers, whereas a fixed-stroke SAI cylinder would require physical shimming or swapping to achieve the same precision.
For replacement, match the 32 mm bore, 240 mm stroke, 10 mm adjuster, PT G1/8 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting the FB, CA, CB, and CR footprints. Since the 240 mm stroke approaches the mid-range for this bore, ensure your setup handles side loads; while the 12 mm rod with an M10x1.25 thread offers decent support, long unsupported travels still require an external guide.

- ✓ 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 SAIJ32BX240-10S FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 10 mm from the 240 mm nominal stroke, giving a usable window of 230-240 mm. It functions as a mechanical stop and does not lock the load without live air pressure.
It delivers 402 N of push force and 345 N of pull force at 0.5 MPa. The -S option includes a magnet for position sensing, compatible with AirTAC CMSE reed switches and DMSE electronic solid-state sensors.
