About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX40-30
The AirTAC SAIJ100X40-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 40 mm stroke that can be fine-tuned down by up to 30 mm, yielding a highly precise 10 to 40 mm usable travel window.
This adjustable-stroke design allows operators to set exact end positions at commissioning without adding external stops or swapping cylinders. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE solid-state switches. The rear adjuster acts strictly as a travel stop to set deceleration limits, not as a lock, so live air is required to hold the load.

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 SAIJ100AX40-30 Is Used
Machine Setup & Changeover
Dial in the exact 10 to 40 mm end position during product size changeovers without physically replacing the cylinder or bolting on external stoppers.
Short-Stroke Positioning
Ideal for compact ejection or sorting gates where the effective travel window must be fine-tuned on-site to match the exact distance required by the assembly line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX40-30 the Right Cylinder?
The rear stroke adjustment is ideal for machine setups requiring variable end-stops during product changeovers. For any load-holding requirements without continuous air pressure, this cylinder is insufficient; consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock. To replace this unit, match the 100 mm bore, 40 mm stroke, 30 mm adjustment, PT port, and the standard mounting set.
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 SAIJ100AX40-30 FAQ
The cylinder has a nominal 40 mm stroke, but the external rear adjusting screw allows you to trim the effective travel back by up to 30 mm. This creates a usable travel window of 10 to 40 mm, letting you fine-tune the end position at commissioning without swapping the cylinder.
At 0.7 MPa, the push force increases to 5497 N.
