About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-40S
The AirTAC SAIJ80X200-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 200 mm nominal travel by up to 40 mm for a precise 160-200 mm usable window. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports AirTAC CMSE reed and DMSE electronic solid-state switches for exact position detection.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during product changeovers or commissioning fine-tuning. The rear screw acts purely as a travel stop and works in tandem with variable air cushions at both ends to decelerate the load, but it does not hold the load without live air pressure. For load-holding requirements without continuous pneumatic pressure, consider the SAIL or BSAI series instead.

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 SAIJ80AX200-40S Is Used
Variable End-Stop Machining
Dial in the 160-200 mm retract position precisely during machine setup to accommodate different part lengths without changing the cylinder.
Product Changeover Diverter
Quickly adjust the stroke by up to 40 mm on a packaging line to handle varying box sizes on the fly using the rear stopper screw.
Commissioning Fine-Tuning
Trim the effective travel window during initial commissioning to perfect the timing and end-of-stroke deceleration without adding external stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-40S the Right Cylinder?
The adjustable 160-200 mm travel window is ideal for machines that process varying product sizes, allowing operators to set exact retract end positions on the fly. Because the nominal stroke is 200 mm, an external guide is recommended to manage side loads and prevent excessive wear on the rod seals.
To match this ISO 15552 dimensionally interchangeable cylinder for a replacement, verify the 80 mm bore, 200 mm stroke, 40 mm adjustment range, PT port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets found on some other profiles.

- ✓ 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 SAIJ80AX200-40S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the 200 mm nominal stroke by up to 40 mm, creating a 160-200 mm usable travel window. It functions as a mechanical stop to set the end position and does not lock the load without live air.
