About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-100S
The AirTAC SAIJ32X750-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 750 mm nominal stroke that can be fine-tuned down by up to 100 mm, yielding a precise 650-750 mm usable travel window for exact end-position calibration. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance and features a magnet for CMSE or DMSE sensors.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops during product changeovers. The rear adjuster functions strictly as a travel stop to set the retract position, not as a load-holding lock. For applications requiring position holding without live air pressure, an external rod lock or a related SAIL pneumatic lock cylinder is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-100S Is Used
Machine Setup Calibration
Dial in the exact 650-750 mm end position during commissioning without swapping physical components or adding shims.
Product Size Changeover
Quickly adjust the retract stop to accommodate different product lengths on an automated packaging line.
Variable End-Stop Positioning
Use the 100 mm rear adjuster to fine-tune the stroke limit on test fixtures where the exact travel distance varies per run.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-100S the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa with on-the-fly end-position tuning; if your application requires less force, step down is not an option here, but stepping up to the 40 mm bore yields 628 N. The adjustable 650-750 mm window is ideal for machine setups requiring variable end stops without changing the cylinder. To match this ISO 15552 interchangeable cylinder, confirm the 750 mm stroke, 100 mm adjustment, PT tapered ports, SUS304 rod, and the -S magnet.
Because this model features a 750 mm stroke, the 12 mm rod requires external guiding to prevent excessive side-loading and premature seal wear. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
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 SAIJ32BX750-100S 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 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the 750 mm nominal stroke by up to 100 mm, providing a usable travel window of 650-750 mm. It only sets the end position and does not hold the load without live air.
