About the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-10S
The AirTAC SAIJ40X95-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 95 mm stroke that can be fine-tuned down by up to 10 mm, creating an exact 85-95 mm usable travel window for precise commissioning. Delivering 879 N of push force at 0.7 MPa, it handles moderate actuation tasks with reliable variable air cushions at both ends.
This variant features an SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a built-in magnet for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid ports use a PT tapered thread, and the mounting interface strictly supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-10S Is Used
Machine Changeover
Dial in the 85-95 mm travel window during product size transitions without bolting on external stops or changing the cylinder.
End-Position Tuning
Fine-tune the retract end position at commissioning to achieve precise mechanical alignment for assembly tooling.
Variable End Stops
Accommodate slight variations in package sizes on a line by adjusting the rear stopper screw on the fly.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-10S the Right Cylinder?
Select this 40 mm bore cylinder when an application requires 879 N push force at 0.7 MPa but demands variable end-stops during machine setup or product changeover, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your setup requires less force, stepping down to a 32 mm bore yields 563 N; stepping up to a 50 mm bore provides 1374 N. The rear adjuster acts strictly as a travel stop and does not hold the load without live air—always use a SAIL or BSAI locking cylinder for pneumatic load-holding requirements.
To replace an ISO 15552 cylinder, match the 40 mm bore, 95 mm stroke, 10 mm adjustment range, PT G1/4 port, and the -S magnet option. Because the total stroke is under 300 mm, side-loading stress is minimized, though the 16 mm rod and M12x1.25 thread still require external guiding for heavy lateral loads.
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 SAIJ40 Adjustable Cylinder SAIJ40AX95-10S FAQ
At 0.7 MPa operating pressure, this 40 mm bore cylinder provides 879 N of push force and 528 N of pull force. At 0.5 MPa, it delivers 628 N push and 528 N pull.
The rear adjuster screw allows you to shorten the effective travel from the nominal 95 mm down to 85 mm. This creates an 85-95 mm adjustable window for fine-tuning the end position without replacing the cylinder.
