About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX95-50S
The AirTAC SAIJ100X95-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end-of-travel position. With a 95 mm nominal stroke and a 50 mm adjustment range, it provides a highly versatile 45 to 95 mm usable travel window. This bore size delivers substantial thrust, pushing 3927 N at 0.5 MPa and pulling 3681 N, making it well-suited for heavier actuation tasks.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to set the retraction end point and does not lock the load; for holding loads without live air pressure, consider the SAIL or BSAI series.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100AX95-50S Is Used
Machine Changeover
Dial in the exact 45 to 95 mm retraction stop during product size changes without swapping out the entire cylinder or adding external shims.
End-Stop Tuning
Use the rear adjuster to fine-tune the final end position at commissioning, absorbing minor mechanical tolerances in the machine assembly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX95-50S the Right Cylinder?
Select this adjustable-stroke model when your application requires on-the-fly end-position tuning during commissioning or product changeovers, rather than relying on a fixed-stroke SAI cylinder. Because the 95 mm stroke is under 300 mm, side-load risks are moderate, but the M20x1.5 rod thread and 25 mm rod diameter handle reasonable guide loads effectively.
When matching this cylinder to an ISO 15552 interchangeable replacement, verify the 100 mm bore, 45-95 mm adjustable travel, PT tapered port threads, and the -S magnet option. Remember that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.
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 SAIJ100 Adjustable Cylinder SAIJ100AX95-50S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 50 mm, creating a usable travel window between 45 and 95 mm. This allows precise end-position tuning at commissioning without replacing the cylinder.
At 0.7 MPa, the push force increases to 5497 N.
