About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX225-10S
The AirTAC SAIJ32X225-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 225 mm nominal stroke that can be fine-tuned down by up to 10 mm, yielding a usable travel window of 215-225 mm. Delivering 402 N of push force at 0.5 MPa, it features a SUS304 stainless steel rod and a built-in magnet for position sensing.
This adjustable-stroke design allows you to dial in the retract end-position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It supports AirTAC CMSE reed and DMSE electronic sensors, operating reliably at speeds between 30 and 800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX225-10S Is Used
End-Position Tuning
Dial in the exact retract distance within a 215-225 mm window during machine commissioning without swapping out the entire actuator.
Product Changeover
Quickly adjust the stroke by up to 10 mm to accommodate minor size variations on a production line running different components.
Light-Force Positioning
Utilize the 402 N push force and SUS304 rod for precise, corrosion-resistant movement of small to medium payloads.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX225-10S the Right Cylinder?
Choose this 32 mm bore when you need precise 215-225 mm travel and light-force actuation up to 402 N at 0.5 MPa. If your application requires greater thrust, stepping up to the 40 mm bore yields 628 N of push force. The rear adjuster screw acts purely as a travel stop to set deceleration and end-position; it does not hold the load without live air. For load-holding requirements without pneumatic pressure, consider the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 225 mm stroke, PT tapered port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR. Because the 225 mm stroke is moderately long, ensure external guiding is used to prevent excessive rod side-loading.

- ✓ 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 SAIJ32BX225-10S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a usable travel window of 215-225 mm. This lets you fine-tune the end position at commissioning without changing the cylinder or adding external stops.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 801 N.
