About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-20S
The AirTAC SAIJ32X700-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 680 to 700 mm usable travel window, allowing you to dial back the end position by up to 20 mm during commissioning without swapping hardware. In the 32 mm bore class, it yields 402 N of push thrust and 345 N of pull thrust at 0.5 MPa.
This unit features a SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Pneumatic connections use PT tapered threads, and variable air cushions at both ends manage end-of-stroke deceleration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-20S Is Used
Machine Changeover
Quickly fine-tune the 680-700 mm retract position when switching product sizes on a packaging line, avoiding mechanical rebuilds.
End-Stop Calibration
Dial in the exact end position during commissioning to perfect tooling alignment without fabricating custom spacer shims.
Variable Length Diverter
Adjust the stroke window on a sorting diverter to handle varying package lengths on the fly without changing the cylinder.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-20S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa; step up to a 40 mm bore if you need 628 N. The adjustable stroke is ideal for product changeovers on a line, letting you fine-tune the retract stop without adding external physical stops. Remember that the rear adjuster is a travel stop, not a lock—it will not hold the load without live air. For secure load-holding without pressure, consider an external rod lock or the AirTAC SAIL series.
As a dimensionally interchangeable ISO 15552 cylinder, replacement requires matching the 32 mm bore, 700 mm stroke, 20 mm adjustment range, PT port threads, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 700 mm stroke is long relative to the 12 mm rod diameter, an external guide is highly recommended to prevent excessive side-loading and premature seal wear.
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 SAIJ32AX700-20S 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 the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster acts as a stopper that lets you shorten the effective stroke by up to 20 mm, creating a 680 to 700 mm travel window. It sets the end position but does not lock the load without continuous air pressure.
