About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-100
The AirTAC SAIJ100X700-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 700 mm travel by up to 100 mm for a precise 600-700 mm usable window. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during product changeovers, letting operators fine-tune the retract end-position directly at commissioning. It operates at speeds of 30-800 mm/s and uses PT tapered port threads (G1/2) paired with 36 mm variable air cushions at both ends to manage kinetic energy. The rear adjuster acts purely as a travel stop 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 SAIJ100AX700-100 Is Used
Variable End-Stop Forming
Dial in the exact 600-700 mm retract position for metal forming presses where material thickness varies, using the rear adjuster rather than re-shimming the tooling.
Product Size Changeovers
Rapidly adapt a 700 mm stroke transfer pusher on a packaging conveyor to handle different carton lengths by adjusting the travel limit up to 100 mm.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-100 the Right Cylinder?
The 100 mm class is ideal when you need to accommodate slight mechanical variations or product size changes on a line without machining new hard stops. Because the stroke is 700 mm, the M20x1.5 rod thread and 25 mm rod diameter provide substantial rigidity, but an external guide is strongly recommended to prevent excessive side-loading on the long unsupported travel.
For an exact ISO 15552 dimensional replacement, match the 100 mm bore, 700 mm stroke, PT port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that SAIJ omits FB, CA, CB, and CR mounts. If your process requires the load to be held mechanically without continuous live air, this cylinder's air cushion and rear stopper will not suffice; consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock 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 SAIJ100AX700-100 FAQ
The rear adjuster acts as an external stopper that trims the effective travel. For this model, you can shorten the 700 mm nominal stroke by up to 100 mm, providing an adjustable operating window of 600 to 700 mm to fine-tune the retract position without changing the cylinder.
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.9 MPa, the push force increases to 7068 N, with a maximum rated force of 801 kgf at 1.0 MPa.
