About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-40
The AirTAC SAIJ32X105-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel anywhere within a 65-105 mm window. Built with a 32 mm bore, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa. The extruded aluminum barrel features sensor grooves on both sides, providing a true profile cylinder design rather than a traditional tie-rod assembly.
This model uses a 12 mm carbon steel rod with an M10x1.25 thread and a PT G1/8 port. The rear adjustment screw acts purely as a mechanical stop to set the retract end position during commissioning; it does not lock or hold the load without continuous live air pressure. For load-holding requirements, exploring an external rod lock or the AirTAC SAIL series is recommended.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-40 Is Used
Machine Changeovers
Dial in the 65-105 mm travel window during product size transitions to set new retract endpoints without swapping hardware.
End-Position Tuning
Fine-tune the final retract position during initial commissioning using the rear stopper to achieve exact alignment.
Variable End Stops
Create an adjustable mechanical stop for delicate picking or pushing tasks that require precise depth control.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-40 the Right Cylinder?
Choose this 32 mm bore when your application requires the 402 N push force at 0.5 MPa, stepping down from a 40 mm bore that provides 628 N, or up if your layout demands less than 345 N of pull force. An adjustable stroke is selected over a fixed SAI cylinder when you need on-the-fly end-position tuning for product changeovers without adding external stops. To match this ISO 15552 replacement exactly, specify the 32 mm bore, 105 mm stroke, 40 mm adjustment, PT G1/8 port, and your required mounting option from the available SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Because the 105 mm stroke is relatively short, side-load stress is minimal, but always ensure the load is guided to prevent rod binding.
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 SAIJ32X105-40 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster screw lets you shorten the nominal 105 mm stroke by up to 40 mm, providing a usable travel window between 65 and 105 mm. The adjuster functions as a travel stop and requires live air to maintain position.
