About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-100S
The AirTAC SAIJ32X105-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a highly flexible usable travel window of 5 to 105 mm. Delivering 402N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The integrated magnet allows seamless compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors.
By turning the external rear stopper screw, you can dial back the nominal 105 mm stroke by up to 100 mm without swapping the cylinder or adding external stops. This adjuster acts purely as a travel stop and works alongside the variable air cushions at both ends to decelerate the piston; it does not lock or hold the load without live air pressure. For applications requiring position holding, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-100S Is Used
Machine Setup & Changeover
Fine-tune the retract end-position from 5 to 105 mm during machine commissioning or product size changes without physically swapping out the cylinder.
Variable End-Stop Positioning
Dial in the exact required travel distance for delicate assembly tasks, using the rear stopper to set precise mechanical limits.
Corrosive Environment Testing
Leverage the SUS304 stainless steel rod for pilot testing and positioning tasks in environments where standard carbon steel rods would fail.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-100S the Right Cylinder?
Choose this 32 mm bore model when you need precise end-position tuning during commissioning or frequent product changeovers, stepping up from a smaller bore if you require higher thrust. If you need more force, a 40 mm bore provides 628N of push force at 0.5 MPa. This SAIJ variant features a PT tapered port and includes the -S magnet for CMSE/DMSE sensors. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is 105 mm, external side-load guides are less critical, but the 12 mm rod and M10x1.25 thread still require reasonably aligned mounting to prevent premature seal wear.
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 SAIJ32BX105-100S FAQ
The rear adjuster screw acts as a mechanical stop that allows you to shorten the effective stroke by up to 100 mm from the nominal 105 mm, giving you a usable travel window of 5 to 105 mm. It is a travel stop only and does not lock the load without live air pressure.
At an operating pressure of 0.5 MPa, the SAIJ32X105-100-S provides 402N of push force and 345N of pull force. At the maximum pressure of 1.0 MPa, it delivers up to 801N of push force.
