About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-10S
The AirTAC SAIJ32X425-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 415-425 mm usable travel window, letting you dial back the 425 mm nominal stroke by up to 10 mm during machine setup. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa. This specific SKU features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE or DMSE sensor integration.
Because the 425 mm stroke is relatively long for a 32 mm bore, the 12 mm rod should be guided externally to prevent sagging and side-load damage. The rear adjuster acts purely as a travel stop to fine-tune the retract end position without adding external stops. It does not lock the load without live air pressure; use a SAIL or BSAI cylinder for load-holding needs.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-10S Is Used
Machine Setup Calibration
Dial in the exact retract position within the 415-425 mm window during initial machine commissioning without swapping out the entire cylinder.
Product Size Changeover
Quickly adjust the end-stop by up to 10 mm on a packaging line when processing slightly shorter product lengths.
Stainless Rod Positioning
Leverage the SUS304 rod and 402 N push force for precise component placement in environments requiring corrosion resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-10S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when you need precise end-position tuning at commissioning or during a product changeover, rather than relying on a fixed-stroke SAI model. If your application requires more thrust, step up to the 40 mm bore, which provides 628 N of push force at 0.5 MPa. To replace this ISO 15552 cylinder accurately, match the 32 mm bore, 425 mm stroke, 10 mm adjustment, PT tapered ports, and the -S magnet option.
The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR mounts. Given the 425 mm stroke, always pair the cylinder with an external guide rail to handle side loads, as the 12 mm rod and M10x1.25 thread are designed for axial force rather than lateral support.

- ✓ 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 SAIJ32BX425-10S FAQ
The rear adjusting screw lets you shorten the effective stroke by up to 10 mm from the 425 mm nominal length, creating a 415-425 mm travel window. It acts as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
At 0.5 MPa, it provides 402 N of push force and 345 N of pull force. The standard speed range for this 32 mm bore is 30-800 mm/s, and it features a 12 mm rod with an M10x1.25 thread.
