About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-40S
The AirTAC SAIJ80X130-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -40 adjustment code allows you to dial back the 130mm nominal stroke, providing an exact 90-130mm usable travel window for fine-tuning retract end positions.
This model includes a -S magnet for use with AirTAC CMSE reed and DMSE electronic sensors, and uses a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance. The extruded aluminum barrel incorporates sensor grooves on both sides. You can fine-tune the travel end at commissioning via the rear stopper, which acts as a deceleration point alongside the variable air cushions, rather than serving as a load lock.

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 SAIJ80AX130-40S Is Used
Machine Setup Changeover
Quickly reconfigure the 90-130mm retract position during product size changeovers without physically replacing the cylinder or bolting on external stopper blocks.
Variable End-Stop Positioning
Dial in the exact clamping or pressing end-point during commissioning using the rear screw, accommodating part tolerances on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-40S the Right Cylinder?
Choose this 80mm bore when an application demands higher thrust than the 63mm bore (1559N at 0.5 MPa) but does not require the full output of a 100mm cylinder (3927N). The adjustable 90-130mm travel window is ideal for product changeovers on a line, allowing you to shift the end-stop without swapping the cylinder or adding external stops. The PT tapered port threads and standard ISO 15552 mounting dimensions ensure straightforward replacement.
For load-holding without live air pressure, note that the rear adjuster is strictly a travel stop, not a lock; you would need an external rod lock, a pilot-operated check valve, or a related SAIL lock cylinder. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the 25mm rod and M20x1.5 thread handle high side loads, this cylinder still relies on external guides for stability in long-stroke setups.
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 SAIJ80AX130-40S FAQ
At 0.7 MPa, the push force increases to 3518N.
The -40 code means the 130mm nominal stroke can be shortened by up to 40mm via a rear adjusting screw, creating a 90-130mm usable travel window. This stopper sets the end position but does not lock the load without live air pressure.
