About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX850-30S
The AirTAC SAIJ100X850-30-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 850 mm stroke with a 30 mm adjustment range, giving you a precise 820-850 mm usable travel window for exact end-position tuning during commissioning.
This variant includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered ports. The extruded aluminum barrel features dual sensor grooves, and the included magnet (-S) directly supports AirTAC CMSE reed and DMSE solid-state switches for precise position detection.

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 SAIJ100BX850-30S Is Used
Machine Changeovers
Dial in the 820-850 mm travel window during product-size changeovers to set new end positions without physically swapping the cylinder.
Variable End Stops
Fine-tune the retract position on heavy conveyor diverters where the exact 850 mm stroke needs a 30 mm trim to align perfectly.
Assembly Line Setup
Adjust the stroke during initial commissioning to compensate for mechanical tolerances without installing external stopper blocks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX850-30S the Right Cylinder?
The 30 mm rear adjuster allows you to fine-tune the retract end-stop without swapping cylinders or adding external stops, which is far more efficient than using a fixed-stroke SAI model. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder. Because the 850 mm stroke is long, an external guide is recommended to prevent excessive side-load on the 25 mm piston rod. Mounting options include 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 SAIJ100BX850-30S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop that shortens the effective travel. For this 850 mm stroke model, it creates a usable 820-850 mm window, allowing precise end-position tuning without changing the cylinder.
