About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX95-40
The AirTAC SAIJ32X95-40 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, engineered to fine-tune end positions at commissioning. By turning the external stopper, you can dial back the 95 mm nominal stroke by up to 40 mm, creating a precise 55-95 mm usable travel window without swapping the unit or adding external stops.
Belonging to the 32 mm bore class, it yields 402 N of push force and 345 N of pull force at 0.5 MPa. It features a SUS304 stainless steel rod for corrosion resistance, a 12 mm rod with an M10x1.25 thread, and a G1/8 port. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX95-40 Is Used
Machine Setup Changeover
Dial in the exact 55-95 mm retract position during machine changeovers without physically replacing the cylinder or bolting on external stops.
Variable End-Position Tuning
Fine-tune the stroke end-point at commissioning to absorb minor mechanical tolerances and achieve precise product placement.
Product Size Adjustments
Accommodate varying product lengths on a conveyor line by adjusting the rear stopper to shift the effective travel window on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX95-40 the Right Cylinder?
Select this 32 mm bore when you need variable end-stops for product changeovers rather than a fixed-stroke SAI cylinder. If your application requires higher force, stepping up to the 40 mm bore provides 628 N of push force at 0.5 MPa. Because the 95 mm stroke is under the 300 mm threshold, side-load risks are minimal, but the 12 mm rod still requires an external guide for heavy lateral loads.
When matching an ISO 15552 replacement, verify the 95 mm stroke, 40 mm adjustment range, PT tapered port thread, and the absence of a magnet (-S). The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. For load-holding without live air, consider the SAIL or BSAI series instead.
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 SAIJ32BX95-40 FAQ
At 0.5 MPa operating pressure, the 32 mm bore generates 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you trim the 95 mm nominal stroke back by up to 40 mm, providing a usable travel window of 55 to 95 mm for fine-tuning end positions.
