About the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX700-100
The AirTAC SAIJ40X700-100 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 700mm stroke. An integrated rear adjusting screw provides a 100mm trim range, yielding a usable travel window of 600-700mm. This mechanism allows you to dial in the exact retract end-position during commissioning without adding external stopper blocks.
This variant features a SUS420J2 stainless steel rod for superior corrosion resistance and uses PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts purely as a mechanical travel stop to set the end position; it does not lock or hold the load without sustained air pressure.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 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 SAIJ40 Adjustable Cylinder SAIJ40AX700-100 Is Used
Variable End-Stop Machining
Fine-tune the 600-700mm retract position during machine setup to accommodate different part lengths without changing cylinders.
Product Changeover Diverter
Quickly adjust the stroke by up to 100mm when switching between product sizes on a packaging line, ensuring precise diverting.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX700-100 the Right Cylinder?
If your setup demands less than 402N, step down to a 32mm bore; if you need over 982N, step up to a 50mm bore. The 100mm adjustment range is ideal for product changeovers on a line, letting you alter the effective stroke from 600mm to 700mm on the fly instead of physically swapping the cylinder for a different fixed-stroke SAI unit.
Because the 700mm stroke is relatively long, the 16mm rod and M12x1.25 thread will experience amplified side-loading if the load is unsupported. Always guide the load externally to prevent rod binding. For applications that must hold position without live air pressure, this cylinder is insufficient; select an AirTAC SAIL or BSAI locking cylinder instead. To replace an ISO 15552 unit, match the 40mm bore, 700mm stroke, 100mm adjustment, PT port, and desired mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ40 Adjustable Cylinder SAIJ40AX700-100 FAQ
It features a rear adjusting screw that allows you to shorten the effective stroke by up to 100mm. This creates a usable travel window of 600-700mm, letting you set the exact retract end-position during commissioning without external stops.
At 0.7 MPa, the push force increases to 879N.
