About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX70-10
The AirTAC SAIJ100X70-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position without adding external stops. It provides a usable travel window of 60 to 70 mm, letting you dial in the exact retract distance during machine commissioning.
This variant features a SUS304 stainless steel rod for superior 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. It supports a speed range of 30-800 mm/s and uses self-centering variable air cushions at both ends to decelerate the payload smoothly.

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 SAIJ100BX70-10 Is Used
Machine Changeover
Dial in the 60-70 mm stroke window during product size changes to set exact end positions without repositioning the cylinder.
End-Position Tuning
Fine-tune the retract stop during commissioning to compensate for mechanical tolerance variations in the fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX70-10 the Right Cylinder?
Choose this 100 mm bore actuator when your application requires high thrust—up to 5497 N at 0.7 MPa—and precise mechanical end-stop tuning. If you need less force, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa, while a 125 mm bore provides 8590 N for heavier payloads. The integrated 10 mm rear adjuster is ideal for product changeovers, allowing you to shorten the stroke on the fly without swapping the cylinder or bolting on external stopper blocks.
Because this is a double-acting cylinder, the rear adjuster and air cushions only set the travel end and decelerate the load; they do not hold the position without live air pressure. For load-holding requirements without continuous air, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external pilot-operated check valve. This SAIJ model is dimensionally interchangeable per ISO 15552 and is available with Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting brackets.
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 SAIJ100BX70-10 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 70 mm down to as little as 60 mm. This creates a 60-70 mm usable window for fine-tuning the end position at commissioning without swapping the cylinder.
