About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX850-100
The AirTAC SAIJ100X850-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 750-850mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This specific configuration uses a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It does not lock the load or hold position 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 SAIJ100AX850-100 Is Used
Machine Changeovers
Dial in the 750-850mm travel window during product size transitions without physically swapping the cylinder or reengineering fixed stop positions.
Variable End-Stop Tuning
Set precise retract distances during initial machine commissioning, using the 100mm adjustment range to compensate for mechanical tolerance stack-up.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX850-100 the Right Cylinder?
Choose this 100mm bore cylinder when your application requires substantial thrust—up to 7068N at 0.9 MPa—but you need flexibility in the final end position. The 100mm adjustability range is ideal for product-size changeovers on a line. If you need less force, stepping down to an 80mm bore yields 2513N at 0.5 MPa. The G1/2 port and 30-800mm/s speed range provide high flow capacity.
Because the 850mm stroke is long, the 25mm rod diameter and M20x1.5 rod thread carry significant side loads, but an external guide is still required to prevent rod binding. This SAIJ model is dimensionally interchangeable per ISO 15552 standards and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. For load-holding without live pressure, consider the SAIL or BSAI series instead.
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 SAIJ100AX850-100 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 100mm, creating a 750-850mm travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air.
At 0.7 MPa, the push force increases to 5497N.
