About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX650-100
The AirTAC SAIJ100X650-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 650 mm travel back by up to 100 mm, creating a precise 550-650 mm usable window.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this model uses PT tapered port threads (G1/2) and operates at speeds between 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, while the adjustable stopper functions purely as an end-position 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 SAIJ100BX650-100 Is Used
Machine Setup & Changeover
Dial in the exact 550-650 mm end-stop during product size changeovers without machining new stopper blocks or swapping the cylinder.
Long-Stroke Assembly Pressing
Use the long travel and fine rear adjustment to set precise pressing depths for varying component heights on an assembly line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX650-100 the Right Cylinder?
The integrated rear adjuster is selected over a fixed-stroke SAI cylinder when you need fine end-position tuning during commissioning or product changeover without swapping out the physical cylinder.
Because the 650 mm stroke is relatively long, an external guide is recommended to prevent excessive side-loading on the 25 mm rod. For load-holding without continuous air pressure, note that this cylinder's adjuster is not a lock; you would need to specify an SAIL or BSAI variant, or use an external rod lock. This unit is dimensionally interchangeable per ISO 15552 with mounting options including Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100BX650-100 FAQ
If you increase the operating pressure to 0.9 MPa, the push force reaches 7068 N.
The rear adjusting screw acts as an external stopper, allowing you to shorten the 650 mm nominal stroke by up to 100 mm, resulting in a usable travel window of 550-650 mm. It only sets the end position and does not lock the load without live air.
