About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX225-100
The AirTAC SAIJ32X225-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the 225 mm nominal travel by up to 100 mm. This creates a highly flexible 125-225 mm usable window, letting you fine-tune the retract end position at commissioning without adding external stops. It delivers 724 N of push force at 0.9 MPa, making it suitable for lighter-duty work.
This model is equipped with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads (G1/8). The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts only as a travel stop to set deceleration; it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX225-100 Is Used
Machine Changeover
Dial in the exact retract position during product size changes without swapping the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the 125-225 mm travel window during commissioning to perfect the approach distance on lightweight tooling.
Variable End Stops
Set a precise mechanical stop for repetitive light-force clamping tasks where a fixed 225 mm stroke would be too long.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX225-100 the Right Cylinder?
Choose this 32 mm bore when your application requires precise variable end-stops within a 125-225 mm window, rather than committing to a fixed-stroke SAI cylinder. If your setup needs more push force at 0.5 MPa, stepping up to the 40 mm bore yields 628 N. Because the 225 mm stroke exceeds 300 mm? No, but for any long unsupported travel, an external guide is recommended to manage side-load, as the 12 mm rod and M10x1.25 thread carry limited lateral loads. The rear adjuster is a stop, not a lock; for true load-holding without live pressure, consider the SAIL or BSAI series. This cylinder is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32BX225-100 FAQ
The rear adjuster lets you shorten the 225 mm nominal stroke by up to 100 mm, providing a usable travel window of 125-225 mm. It acts as a mechanical stop to tune the retract end position and does not lock the load without live air.
It provides 402 N of push force at 0.5 MPa and up to 724 N at 0.9 MPa. The pull force is 345 N at 0.5 MPa. It operates at speeds of 30-800 mm/s.
