About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX145-40S
The AirTAC SAIJ80X145-40-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a usable travel window of 105 to 145 mm, allowing you to dial back the nominal 145 mm stroke by up to 40 mm during commissioning without adding external stops.
This variant includes a magnetic piston for position detection and uses a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance. The extruded aluminum barrel features sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic switches. It utilizes PT tapered ports and includes adjustable air cushions at both ends to decelerate moving loads smoothly.

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 SAIJ80AX145-40S Is Used
Machine Setup Calibration
Fine-tune the 145 mm stroke down to 105 mm during initial commissioning to achieve precise end-positioning without swapping out the entire cylinder.
Product Size Changeover
Quickly adapt the effective travel distance on packaging lines when running different product sizes, using the 40 mm rear adjuster to set new stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX145-40S the Right Cylinder?
The adjustable 105-145 mm window is ideal for product changeovers or fine-tuning end positions on the fly. Because the rear adjuster acts only as a travel stop and the air cushions manage deceleration, this cylinder cannot hold a load without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series instead.
As an ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR mounts. The operating speed ranges from 30 to 800 mm/s. Although the 145 mm stroke is relatively short, always verify that the load is adequately guided to prevent excessive side loads on the rod and front cap.
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 SAIJ80AX145-40S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 105 to 145 mm. The adjuster acts as a mechanical stop to set the end position and does not lock or hold the load without continuous air pressure.
