About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-100S
The AirTAC SAIJ32X475-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a generous usable travel window of 375 to 475 mm, allowing you to dial in the exact end position during commissioning without adding external stops. Equipped with a SUS420J2 stainless steel rod and a -S magnet, it delivers a maximum push force of 724 N at 0.9 MPa.
This model features PT tapered port threads and integrated dual sensor grooves compatible with CMSE reed and DMSE electronic switches. The rear adjuster functions strictly as a travel stop for end-position tuning, not a load-holding lock. For applications requiring position retention without live air pressure, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-100S Is Used
Variable End-Stop Tuning
Dial in the retract distance precisely within the 375-475 mm window during machine commissioning to accommodate varying product lengths.
Product Size Changeovers
Quickly adjust the effective stroke on packaging lines handling different carton sizes without physically replacing the cylinder.
Sensor-Driven Positioning
Leverage the built-in magnet with DMSE electronic sensors to confirm the adjusted end position in automated assembly lines.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-100S the Right Cylinder?
Choose this 32 mm bore when your application requires up to 724 N of push force at 0.9 MPa. If your setup needs greater thrust, stepping up to the 40 mm bore yields 1130 N. The 100 mm adjustment range is ideal for product lines running multiple sizes, letting you fine-tune the retract distance on the fly rather than swapping out a fixed-stroke SAI cylinder.
Because this cylinder uses a 12 mm rod and has a 475 mm stroke, it is susceptible to side-loading forces. Always use an external guide to support the load and prevent premature seal wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles found on some other ISO 15552 cylinders.

- ✓ 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 SAIJ32AX475-100S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 375 to 475 mm, which is set at commissioning without needing to swap the cylinder.
Operating at 0.9 MPa, this cylinder generates a maximum push force of 724 N and a pull force of 345 N at 0.5 MPa. The maximum operating pressure is 1.0 MPa.
