About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX110-20S
The AirTAC SAIJ32X110-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 90-110 mm usable travel window by trimming up to 20 mm off the 110 mm nominal stroke, enabling precise end-position tuning at commissioning. In the 32 mm bore class, it delivers 563 N of push force and 345 N of pull force at 0.5 MPa.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports position detection via AirTAC CMSE reed or DMSE electronic solid-state switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX110-20S Is Used
Product Changeovers
Dial in the 90-110 mm travel window during format changes on packaging lines, allowing rapid size adjustments without replacing the actuator.
End-Stop Calibration
Fine-tune the exact retract position during machine commissioning to prevent crashes and ensure precise mechanical alignment.
Sensor Positioning
Leverage the integrated magnet and dual sensor grooves to mount CMSE or DMSE switches exactly where the adjusted stroke ends.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX110-20S the Right Cylinder?
Choose this 32 mm bore when an application requires fine-tuning the retract end-stop without swapping cylinders or adding external stops. If your process demands less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 879 N push force at 0.5 MPa. Remember that the rear adjuster acts strictly as a travel stop, not a lock; the SAIJ cannot hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.
When specifying an exact ISO 15552 replacement, verify the 32 mm bore, 110 mm stroke, 20 mm adjustment range, PT port thread, and the required -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles found on some standard cylinders.
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 SAIJ32BX110-20S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 110 mm nominal stroke by up to 20 mm, creating a 90-110 mm usable travel window. It functions as a stop and not a lock, meaning the cylinder still requires live air pressure to hold its position.
At 0.5 MPa operating pressure, this cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
