About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-75S
The AirTAC SAIJ100X700-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear-mounted stroke adjuster, providing a usable travel window of 625 to 700 mm. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-travel detection.
Unlike a fixed-stroke SAI cylinder, this model allows you to fine-tune the retract end position at commissioning or during product changeover without swapping the cylinder or adding external stops. The rear adjuster functions purely as a mechanical stop to set the travel limit and works in tandem with the adjustable air cushions at both ends; it does not lock or hold the load without live air pressure. For operations requiring load-holding without continuous air, a SAIL or BSAI variant is required.

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 SAIJ100BX700-75S Is Used
Machine Setup Changeover
Dial in the exact retract distance from 625 to 700 mm during product size transitions without disassembling the pneumatic circuit or adding external mechanical stops.
Variable End-Stop Positioning
Ideal for diverter arms on packaging lines where the end position must be fine-tuned on the fly to accommodate varying package depths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-75S the Right Cylinder?
Selecting this 100 mm bore cylinder makes sense when your application demands high thrust—up to 3927 N at 0.5 MPa or 7068 N at 0.9 MPa—combined with the flexibility of a 75 mm adjustable travel window. If your force requirements are lower, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, while moving up to a 125 mm bore provides 6136 N. The PT tapered port is G1/2, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations, omitting FB, CA, CB, and CR options.
Because this unit features a 700 mm stroke, the 25 mm rod and M20x1.5 rod thread will experience significant side-loading if the load is unsupported. An external guide rail is strongly recommended to prevent premature seal wear and binding. To replace an ISO 15552 cylinder, match the 100 mm bore, 700 mm stroke, 75 mm adjustment, PT port, and the -S magnet requirement.
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 SAIJ100BX700-75S FAQ
At the maximum operating pressure of 1.0 MPa, it delivers 801 kgf.
A rear-mounted screw stopper allows you to mechanically shorten the effective stroke by up to 75 mm from the nominal 700 mm, giving a usable travel window of 625 to 700 mm for fine-tuning end positions.
