About the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-30S
The AirTAC SAIJ40X95-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 65-95 mm usable travel window, allowing you to dial back the 95 mm nominal stroke by up to 30 mm during commissioning. It delivers a 0.7 MPa push force of 879 N and a pull force of 528 N.
This unit includes a magnet for CMSE reed and DMSE electronic sensors. It uses a SUS420J2 stainless steel rod for corrosion resistance and a PT tapered port thread. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-30S Is Used
End-Stop Calibration
Dial in the exact 65-95 mm travel window during machine setup to absorb mechanical tolerances without swapping the cylinder.
Product Changeover
Quickly adjust the retract end-position on a packaging line when switching to a different package length.
Assembly Pressing
Fine-tune the pressing depth of pins or rivets on the fly to ensure consistent joint quality.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-30S the Right Cylinder?
Choose this adjustable-stroke model when a fixed SAI cylinder cannot absorb mechanical tolerances or product-size changes without adding external stops. If you need less force, the 32 mm bore offers 563 N at 0.7 MPa; if your load requires more, step up to the 50 mm bore for 1374 N. Remember that the rear adjuster is a travel stop, not a lock; for position holding without live air, select an SAIL or BSAI cylinder. To replace an ISO 15552 unit, match the 40 mm bore, 95 mm stroke, 30 mm adjustment, PT port, and -S magnet.

- ✓ 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 SAIJ40 Adjustable Cylinder SAIJ40AX95-30S FAQ
The rear adjuster screw lets you shorten the effective travel from the 95 mm nominal stroke down to 65 mm. This creates a 30 mm adjustable window for fine-tuning the end position at commissioning without adding external stops.
At a 0.7 MPa operating pressure, the SAIJ40X95-30-S generates a push force of 879 N and a pull force of 528 N. The maximum force at 1.0 MPa is 128 kgf.
