About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX650-100S
The AirTAC SAIJ80X650-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The integrated -S magnet supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection.
This unit is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance and carries a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and the adjustable stopper functions purely as a travel end-stop, meaning it will not hold a load safely without continuous live air pressure.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX650-100S Is Used
Product Changeovers
Quickly shift the retract end-stop by up to 100mm during packaging line format changes, eliminating the need to bolt on external physical stops.
Variable Position Diverters
Fine-tune the actuation point of a diverter arm over the 550-650mm travel window to accommodate different package sizes on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX650-100S the Right Cylinder?
The 100mm adjustment range is ideal for product changeovers on a packaging line, allowing operators to reposition the retract end-stop rapidly instead of installing external physical stops. Because the nominal stroke is 650mm, an external guide is highly recommended to prevent excessive side-loading on the extended rod.
For a direct ISO 15552 replacement match, verify the 80mm bore, 650mm stroke, 100mm adjustment, PT port thread, and the -S magnet requirement. Remember that the rear adjuster only sets the travel end position and decelerates the load alongside the air cushions; it does not function as a lock. If your setup requires true load-holding without live air, consider the AirTAC SAIL or BSAI series instead. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ80 Adjustable Cylinder SAIJ80BX650-100S FAQ
It operates at a speed range of 30-800 mm/s and features a maximum operating pressure of 1.0 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 650mm down to 550mm. This creates a 550-650mm adjustable travel window for fine-tuning the retract position at commissioning.
