About the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-30
The AirTAC SAIJ40X95-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 65 to 95 mm. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This variant uses an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The rear adjuster acts purely as a mechanical stop to dial in the end position during commissioning; it does not lock the load without live air pressure. Threaded PT air ports and adjustable air cushions at both ends manage impact deceleration.

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 SAIJ40AX95-30 Is Used
Machine Changeover
Dial in the 65 to 95 mm stroke window during product size changes without swapping the cylinder or adding external stop blocks.
End-Position Tuning
Fine-tune the retract end position at commissioning using the rear screw, absorbing mechanical tolerances on the fixture.
Variable End Stops
Adjust the travel distance on the fly for conveyor diverters or sorting gates that require flexible positioning limits.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX95-30 the Right Cylinder?
The 30 mm adjustment range is ideal for product changeovers on a line. For load-holding without continuous air pressure, consider an AirTAC SAIL or BSAI series cylinder instead. When replacing an ISO 15552 cylinder, verify the 40 mm bore, 95 mm stroke, 30 mm adjustment, PT G1/4 ports, and the required mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
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 SAIJ40AX95-30 FAQ
At 0.7 MPa, the push force increases to 879 N.
The rear adjuster screw lets you shorten the 95 mm nominal stroke by up to 30 mm, creating a usable travel window of 65 to 95 mm. It functions as a mechanical stop for end-position tuning and requires live air to hold the load.
