About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX140-100S
The AirTAC SAIJ80X140-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet enables precise position sensing using AirTAC CMSE reed or DMSE electronic solid-state switches installed along the dual sensor grooves.
This specific SKU features a 140 mm nominal stroke paired with a generous 100 mm adjustment range, yielding a usable travel window of 40 to 140 mm. The rod is constructed from SUS420J2 stainless steel (code A) for enhanced durability against moisture, and the PT tapered port threads ensure a tight pneumatic seal at the G3/8 interface.

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 SAIJ80AX140-100S Is Used
Variable End-Stop Calibration
Dial in the exact travel distance from 40 to 140 mm during machine commissioning to accommodate multiple product sizes on a single line without physical hardware changes.
Heavy-Duty Machine Setup
Leverage the 80 mm bore power and SUS420J2 stainless steel rod to fine-tune the clamping reach on heavy industrial machinery during initial installation.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX140-100S the Right Cylinder?
Selecting this 80 mm bore cylinder is ideal when an application demands a wide dynamic stroke window rather than a fixed end position. For higher force, a 100 mm bore provides 3927N. The 100 mm adjuster allows operators to dial in the exact end-of-stroke position during machine setup or product changeover without swapping hardware.
To replace this cylinder in an ISO 15552 system, match the 80 mm bore, 140 mm stroke, 100 mm adjustment, PT port threads, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster acts solely as a mechanical stop to set deceleration; it does not hold the load without live air. For true load-holding without pressure, utilize a SAIL pneumatic lock or an external rod lock.
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 SAIJ80AX140-100S FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjusting screw acts as a mechanical stop that allows you to trim the effective travel back by up to 100 mm. This creates a usable stroke window of 40 to 140 mm, enabling fine-tuning of the end position at commissioning without adding external stops.
