About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-10S
The AirTAC SAIJ32X325-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 325 mm nominal stroke that can be fine-tuned down by up to 10 mm, giving you a precise 315-325 mm usable travel window during commissioning. In the 32 mm bore class, it delivers 402 N of push force at 0.5 MPa.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE or DMSE sensors. Because the stroke is 325 mm, the 12 mm rod should be guided externally to prevent excessive side-loading. 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 SAIJ32BX325-10S Is Used
Commissioning Calibration
Dial in the exact 315-325 mm end-stop during machine setup to perfect product positioning without adding external stops.
Product Changeover
Quickly adjust the rear screw by up to 10 mm to accommodate slight variations in part sizes on a manufacturing line.
Corrosive Positioning
Leverage the SUS304 stainless steel rod for reliable actuation in light-duty environments requiring precise stroke limits.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-10S the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa with exact end-position tuning; if your application requires less force, dropping down is not an option in this size, but stepping up to a 40 mm bore yields 628 N. The adjustable stroke is ideal for machine setups requiring variable end-stops without swapping cylinders, unlike a fixed-stroke SAI. For load-holding without continuous air pressure, this cylinder is insufficient as the rear adjuster is only a stop, not a lock; consider an SAIL or BSAI model instead.
To replace an ISO 15552 cylinder, match the 32 mm bore, 325 mm stroke, 10 mm adjustment, PT tapered port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Given the 325 mm stroke, always use an external guide to support the load and protect the rod seal.
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 SAIJ32BX325-10S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster screw allows you to shorten the 325 mm nominal stroke by up to 10 mm, creating a 315-325 mm travel window. It functions as a mechanical stop and does not lock the load without air pressure.
