About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-50
The AirTAC SAIJ100X700-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 650 to 700 mm, allowing you to dial back the nominal 700 mm stroke by up to 50 mm during commissioning without adding external stops.
This unit uses a SUS420J2 stainless steel rod for improved corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a travel stop to fine-tune the end position and does not lock 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 SAIJ100AX700-50 Is Used
Machine Changeover
Fine-tune the 650-700 mm travel window during product size changes to set precise end positions without mechanical modifications.
Long-Stroke Diverting
Actuate long-distance sorting gates where a 700 mm stroke is needed, but the exact 50 mm adjustment window handles varying product lengths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-50 the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust, such as 5497 N at 0.7 MPa. If your force requirements are lower, stepping down to a 63 mm bore yields 2182 N at the same pressure, while staying within the 30-800 mm/s speed range. The adjustable stroke is ideal for machine changeovers where the exact end-of-travel position needs slight tuning without swapping the cylinder.
For a direct ISO 15552 replacement, match the 100 mm bore, 700 mm stroke, 50 mm adjustment, PT port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 700 mm, the 25 mm rod diameter and M20x1.5 rod thread provide rigidity, but an external guide is recommended to prevent excessive side-loading on long unsupported travels. For load-holding without live air, consider the SAIL or BSAI series instead of relying on the adjuster.
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 SAIJ100AX700-50 FAQ
It can deliver up to 801 kgf at the maximum operating pressure of 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 700 mm down to 650 mm. It fine-tunes the retract end position but does not hold the load without continuous air pressure.
