About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX850-10S
The AirTAC SAIJ100X850-10-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster. This variant includes a magnet for CMSE / DMSE sensors and uses a SUS420J2 stainless steel rod for enhanced corrosion resistance.
The rear adjuster acts purely as a travel stop to fine-tune deceleration and end-position; it is not a lock and will not hold the load without live air pressure. For load-holding without continuous air, an external rod lock or a SAIL pneumatic lock cylinder is required. The extruded aluminum barrel integrates sensor grooves on both sides, and the M20x1.5 rod thread provides a robust interface for long-stroke actuation.

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 SAIJ100AX850-10S Is Used
Machine Changeover
Fine-tune the 840-850 mm retract position on the fly during product size transitions without swapping out the entire actuator.
Variable End Stops
Dial in the exact 10 mm adjustment window to set precise deceleration points for heavy conveyor diverters or stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX850-10S the Right Cylinder?
The 10 mm rear adjustment is ideal for machinery requiring precise end-stop tuning during product changeover. Because the usable travel is 840-850 mm, it provides exact positioning flexibility without replacing the cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 850 mm stroke, PT tapered port threads, and the -S magnet requirement. Given the 850 mm stroke exceeds standard short sizes, an external guide is strongly recommended to prevent rod side-loading and premature wear. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ100AX850-10S FAQ
At 0.9 MPa, the push force increases to 7068N.
The rear adjuster screw acts as a stopper that lets you shorten the effective stroke from 850 mm down to 840 mm. This allows precise end-position tuning at commissioning without adding external stops.
