About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-40
The AirTAC SAIJ100X700-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. By turning the external adjustment screw, you can trim the nominal 700mm stroke back by up to 40mm, creating a precise 660-700mm usable travel window for exact end-position tuning.
This model features a SUS420J2 stainless steel rod (option A) for heightened corrosion resistance and uses PT tapered port threads with a G1/2 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for dead-load holding, 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 SAIJ100AX700-40 Is Used
Variable End-Stop Tuning
Dial in the 660-700mm travel window during machine setup to perfectly position parts without physically swapping the cylinder or bolting on external stoppers.
Product Changeover
Quickly adapt the retract end-position on a packaging line when product sizes change, using the rear screw to trim the stroke by up to 40mm.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-40 the Right Cylinder?
The adjustable stroke is selected over a fixed SAI cylinder when you need to fine-tune the retract end-position during machine commissioning or product changeover without adding external stops.
Because the 700mm stroke is relatively long, the 25mm rod diameter should be paired with an external guide to handle side loads and prevent rod deflection. To match this exact ISO 15552 interchangeable replacement, specify a 100mm bore, 700mm stroke, 40mm adjustment, PT port thread, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set (the SAIJ series omits FB, CA, CB, and CR mounts).
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 SAIJ100AX700-40 FAQ
The rear adjuster acts as a mechanical stop that allows you to shorten the effective travel from the nominal 700mm down to as little as 660mm, giving you a 660-700mm window for fine-tuning. Note that this stop does not lock or hold the load without continuous air pressure.
