About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-75S
The AirTAC SAIJ32X700-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 625 to 700 mm usable travel window, allowing you to trim the nominal 700 mm stroke by up to 75 mm during commissioning without adding external stops. In the 32 mm bore class, it delivers 402 N of push force at 0.5 MPa and 563 N at 0.7 MPa, making it suitable for lighter-duty positioning tasks.
This SKU features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides. It uses a PT tapered G1/8 port and offers adjustable air cushions at both ends to manage impact energy. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-75S Is Used
Machine Changeover
Dial in the 625-700 mm travel window during product size transitions to set exact retract positions without swapping cylinders.
End-Position Tuning
Fine-tune the final retract point at commissioning using the rear stopper, avoiding the need to bolt on external physical stops.
Light-Force Positioning
Leverage the 563 N push force at 0.7 MPa for lighter-duty automated handling tasks requiring precise variable end-stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-75S the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning on a 700 mm stroke, stepping up from a smaller unit or down from a 40 mm bore (which provides 879 N push at 0.7 MPa) if your force requirements are lower. An adjustable stroke is ideal for product changeovers on a line where the exact end-of-stroke varies by up to 75 mm. Because the stroke is 700 mm, an external guide is highly recommended to prevent excessive side-loading on the 12 mm rod. For applications requiring the load to be held without continuous air pressure, this cylinder is insufficient as the adjuster is only a stop; consider an SAIL or BSAI locking cylinder instead. To match this ISO 15552 replacement, specify: 32 mm bore, 700 mm stroke, 75 mm adjustment, PT G1/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and a magnet (-S).

- ✓ 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 SAIJ32BX700-75S FAQ
At 0.5 MPa, the 32 mm bore 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 lets you shorten the effective travel from the 700 mm nominal stroke down to 625 mm. It functions as a mechanical stop to set the retract position, not a lock, so it cannot hold the load without live air pressure.
