About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-75
The AirTAC SAIJ100X950-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 875 to 950 mm, allowing you to dial back the nominal stroke by up to 75 mm during commissioning. This bore size delivers substantial thrust, pushing 7068 N at 0.9 MPa.
Equipped with a SUS420J2 stainless steel rod (material code A) and a PT tapered port thread, it handles demanding environments. The extruded aluminum barrel includes sensor grooves on both sides, though sensors require adding a -S magnet. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure.

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 SAIJ100AX950-75 Is Used
Machine Setup Tuning
Dial in the exact retract position within the 875-950 mm window during initial machine commissioning without machining new hard stops.
Product Changeover
Quickly adjust the end-stop distance to accommodate varying product lengths on a packaging line by turning the rear screw.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-75 the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when you need to fine-tune the retract end-position on the fly, such as during product changeovers, without swapping the cylinder or adding external stops. To hold a load securely without continuous air pressure, use a SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the adjuster.
Because the 950 mm stroke is long, the 25 mm rod and M20x1.5 thread still require an external guide to prevent excessive side-loading. This SAIJ configuration is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAIJ100AX950-75 FAQ
The maximum force at 1.0 MPa is 801 kgf.
A rear mechanical screw stopper lets you shorten the effective travel from the 950 mm nominal stroke down to as little as 875 mm. It acts as an end-position stop and does not lock the load without live air pressure.
