About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX70-10
The AirTAC SAIJ100X70-10 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 70 mm stroke that can be fine-tuned backward by up to 10 mm, creating a precise 60-70 mm usable travel window.
This configuration incorporates a SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU lacks a magnet, adding one enables compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors.

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 SAIJ100AX70-10 Is Used
Machine Setup & Changeover
Dial in the exact 60 to 70 mm end-position during commissioning or product size changes without physically swapping the cylinder.
Variable End-Stop Positioning
Use the 10 mm rear adjustment screw to fine-tune the retract distance for high-thrust pressing or clamping operations.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX70-10 the Right Cylinder?
The adjustable stroke is ideal for product changeovers where the exact end-of-stroke position varies by a few millimeters, saving you from swapping out a fixed-stroke SAI cylinder or adding external stops. Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder.
This model features a PT tapered port thread and the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It is dimensionally interchangeable per ISO 15552 standards. Because the 70 mm stroke is relatively short, side-load stress on the 25 mm rod is minimal, though external guides should always be used to support off-center loads.
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 SAIJ100AX70-10 FAQ
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm. This provides a usable travel window of 60 to 70 mm, allowing you to fine-tune the end position at commissioning without adding external stops.
At 0.9 MPa, the push force increases to 7068 N.
