About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX95-10
The AirTAC SAIJ40X95-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 10 mm. This creates a precise 85-95 mm usable stroke window, enabling exact end-position tuning at commissioning without swapping out the cylinder or adding external stops.
This model is equipped with a SUS304 stainless steel rod for superior corrosion resistance and features an extruded aluminum barrel with sensor grooves on both sides. While it lacks a magnet for position sensing, the grooves remain ready for CMSE reed or DMSE electronic switches if retrofitted later. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock to hold the load without live air pressure.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX95-10 Is Used
Machine Changeover
Dial in the 85-95 mm travel window during product size changes to set new end positions rapidly without mechanical modifications.
End-Stop Tuning
Fine-tune the retract position at commissioning using the rear screw, avoiding the need to fabricate and bolt on external stopper blocks.
Corrosive Environments
Leverage the SUS304 stainless steel rod for reliable actuation in packaging or processing areas exposed to moisture or washdowns.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX95-10 the Right Cylinder?
The adjustable stroke is selected over a fixed SAI cylinder when machine setups require variable end-stops or fine-tuning during product changeovers. To replace this cylinder, match the 40 mm bore, 95 mm stroke, 10 mm adjustment, PT G1/4 port, and SUS304 rod.
Because the stroke is 95 mm, side-load risks are minimal, but always ensure the M12x1.25 rod thread is properly aligned. Remember that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR. For applications requiring the load to be held without continuous air pressure, the plain SAIJ adjuster is insufficient; consider the SAIL pneumatic lock or BSAI clamp-lock cylinder 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 SAIJ40 Adjustable Cylinder SAIJ40BX95-10 FAQ
At 0.7 MPa, the push force increases to 879 N.
The rear adjuster allows you to shorten the 95 mm nominal stroke by up to 10 mm, creating an adjustable travel window of 85 to 95 mm. The adjuster acts as a mechanical stop and does not lock the load without live air.
