About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-30
The AirTAC SAIJ100X65-30 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 65mm nominal stroke that can be dialed back by up to 30mm, providing a usable travel window of 35-65mm for precise end-position tuning during commissioning.
This variant incorporates a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR to streamline the adjustable-stop design.

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 SAIJ100BX65-30 Is Used
Machine Setup Calibration
Dial in the exact 35-65mm travel window during initial machine commissioning to perfect pressing or clamping depth without external spacers.
Product Changeover
Quickly shorten the effective stroke by up to 30mm when switching to a different product size on the line, minimizing downtime.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-30 the Right Cylinder?
Select this 100mm bore actuator when an application requires substantial thrust—up to 5497N at 0.7 MPa—combined with variable end-stop positioning. If 5497N is excessive, stepping down to an 80mm bore yields 3518N at 0.7 MPa; if more force is needed, a 125mm bore provides 8590N. Choose the adjustable SAIJ over a fixed SAI when you need on-the-fly stroke trimming for product changeovers without adding external stops.
For a direct ISO 15552 replacement, match the 100mm bore, 65mm stroke, 30mm adjustment range, PT port threads, and the selected mounting style. Note that this cylinder does not include a magnet (-S). Because the stroke is under 300mm, side-load concerns are minimal, though external guides are still recommended for optimal linear movement. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock or the SAIL/BSAI series.
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 SAIJ100BX65-30 FAQ
At 0.9 MPa, the push force increases to 7068N.
The rear adjuster acts as a mechanical stop that lets you shorten the 65mm nominal stroke by up to 30mm, creating a usable travel window of 35-65mm. It is a travel stop, not a lock, and requires live air to hold the load.
