About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX70-50
The AirTAC SAIJ100X70-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a 70 mm nominal stroke and a 50 mm adjustment range, it provides a highly versatile 20-70 mm usable travel window for precise end-position tuning.
This model features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for future automation upgrades. The rear adjuster acts strictly as a travel stop to decelerate the load and set the end position; it is not a lock and will 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 SAIJ100AX70-50 Is Used
Product Changeover
Dial in the exact end-stop for different part lengths on a single machine without physically swapping cylinders or adding external shims.
Machine Setup
Fine-tune the retract position during commissioning to perfect timing and avoid mechanical crashes before finalizing the fixture.
Variable End Stops
Adjust the effective travel window from 20 to 70 mm on the fly to accommodate varying material thicknesses or positioning depths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX70-50 the Right Cylinder?
Choose this 100 mm bore cylinder when your application requires substantial force but exact end-of-stroke positioning varies between fixtures. If you need less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas a 125 mm bore provides 6136 N for heavier loads. The 50 mm adjustment range is ideal for machine setups requiring frequent product-size changeovers without swapping the physical cylinder.
To replace an ISO 15552 cylinder, match the 100 mm bore, 70 mm stroke, 50 mm adjustment, G1/2 port, and mounting choice from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Because the nominal stroke is under 300 mm, side-load concerns are minimal, but always ensure the load is guided externally to prevent rod binding. For load-holding without live air, consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ100AX70-50 FAQ
At the maximum 1.0 MPa pressure, it can output up to 801 kgf.
The rear adjuster allows you to trim the 70 mm nominal stroke back by up to 50 mm, creating a 20-70 mm usable travel window. The adjuster acts as a stop to set the end position and does not lock the load without continuous air pressure.
