Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-30
The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX85-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 85mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-30
By featuring a 30mm adjustment range, it transforms the fixed 85mm stroke into a precise 55-85mm usable travel window, allowing exact end-position tuning during machine commissioning. This cylinder utilizes an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threading.
Unlike a fixed-stroke SAI, this adjustable model lets you dial in the retract stop without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop and works in tandem with the variable air cushions at both ends to decelerate the load; it does not hold the load without live air pressure. For load-holding requirements, consider an external rod lock or the SAIL/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 SAIJ100AX85-30 Is Used
Machine Setup Changeover
Fine-tune the 55-85mm travel window during product family changeovers to set exact clamping depths without machining new physical spacers.
Variable End-Stop Positioning
Dial in the retract position precisely at commissioning to compensate for mechanical tolerance stack-up across the fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-30 the Right Cylinder?
The 25mm rod diameter and M20x1.5 rod thread provide excellent rigidity, though any application approaching the 85mm stroke should still ensure proper guiding to manage side loads. The integrated rear adjuster is ideal for product-size changeovers on a line, offering a variable end-stop rather than machining custom spacers.
To match this exact configuration for an ISO 15552 replacement, specify the 100mm bore, 85mm stroke, 30mm adjustment range, PT port thread, SUS420J2 rod material, and no magnet. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
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 SAIJ100AX85-30 FAQ
The rear adjuster screw allows you to trim the effective stroke back by up to 30mm, creating a usable travel window of 55-85mm from the nominal 85mm stroke. This stopper sets the end position but does not lock the load without continuous air pressure.
