About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-10
The AirTAC SAIJ32X115-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and utilizes a PT tapered G1/8 port. By turning the rear stopper screw, you can trim the effective travel, creating a precise 105-115mm usable stroke window for exact end-position tuning.
This 32mm bore variant features a SUS304 stainless steel rod for superior corrosion resistance and carries a 12mm rod diameter with an M10x1.25 thread. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on other series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-10 Is Used
End-Position Tuning
Dial in the exact 105 to 115mm retract distance during machine commissioning to perfect part ejection without physically remounting the actuator.
Product Changeover
Quickly adapt a packaging line for different carton sizes by turning the rear stopper screw to shorten the stroke on the fly.
Variable End Stops
Set precise mechanical limits for light-duty assembly presses where a fixed 115mm stroke would overtravel and damage delicate components.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-10 the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires fine-tuning the retract end-position during commissioning or product changeover without swapping out the physical cylinder or adding external stops. If your application needs slightly less force, stepping down is not an option in this frame size, but stepping up to a 40mm bore yields 628N of push force at 0.5 MPa. When matching this for an ISO 15552 replacement, verify the 115mm stroke, the 10mm adjustment range, PT port thread, and the lack of a magnet (-S). Because the stroke is 115mm, side-load risks are minimal, but always ensure linear guidance for heavy loads.
Remember that the rear adjuster functions strictly as a travel stop and works alongside the variable air cushions at both ends. It does not hold the load or maintain position without continuous live air pressure. For applications requiring true load-holding without air pressure, select an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder, or integrate an external pilot-operated check valve.
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 SAIJ32BX115-10 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the nominal 115mm stroke by up to 10mm. This creates a usable travel window of 105-115mm so you can fine-tune the end position at commissioning without changing the cylinder.
At a 0.5 MPa operating pressure, the SAIJ32X115-10 provides 402N of push force and 345N of pull force. It can reach up to 724N of push force at 0.9 MPa.
