Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-40S
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX190-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 190mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-40S
The AirTAC SAIJ80X190-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 190 mm travel by up to 40 mm for a precise 150-190 mm usable window. The barrel features sensor grooves on both sides, and because this unit includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE solid-state switches for end-position detection.
This model features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance compared to standard carbon steel. The integrated rear adjuster acts purely as a mechanical stop to fine-tune the retract position during commissioning or product changeover without adding external stops. It uses a PT tapered G3/8 port and relies on variable air cushions at both ends to decelerate the load 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 SAIJ80AX190-40S Is Used
Variable End-Stop Tuning
Dial in the exact 150-190 mm retract position during machine commissioning to accommodate slight mechanical misalignments without disassembling the cylinder.
Product Size Changeover
Quickly adjust the stroke window on automated packaging lines when switching between different package lengths, minimizing downtime between production runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-40S the Right Cylinder?
The adjustable 150-190 mm stroke is ideal for production lines running slightly varying product sizes, allowing you to fine-tune the end-stop on the fly rather than swapping to a fixed-stroke standard SAI cylinder. To match this ISO 15552 interchangeable unit, specify: 80 mm bore, 190 mm stroke, 40 mm adjust, PT G3/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet.
Because the stroke is 190 mm, the 25 mm rod and M20x1.5 thread provide good rigidity, but long unsupported strokes still require an external guide to prevent side-loading damage. Remember that the rear adjuster and air cushions only set the travel end and decelerate the load; they do not hold the load without live air. For true fail-safe load holding, consider an external pilot-operated check valve or the AirTAC SAIL or BSAI cylinder series.
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 SAIJ80AX190-40S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjusting screw allows you to mechanically shorten the 190 mm nominal stroke by up to 40 mm, creating a usable travel window of 150 to 190 mm. The adjuster acts as a hard stop for end-position tuning and does not lock the load without continuous air pressure.
