About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-30
Its built-in adjusting screw allows you to shorten the effective travel, providing a usable stroke window of 160 to 190mm. This fine-tuning capability is ideal for dialing in end positions during commissioning without adding external stops.
This unit features a SUS420J2 stainless steel rod for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is added later. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80AX190-30 Is Used
Machine Changeover
Quickly dial in the 160-190mm travel window during product size changes without swapping the cylinder or repositioning hard stops.
End-Position Tuning
Fine-tune the retract stroke by up to 30mm at commissioning to perfect the seating pressure of tooling without physical spacers.
Variable Stops
Adjust the stroke end-point on the fly for diverter arms or gates handling packages of varying dimensions on a single line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-30 the Right Cylinder?
The 30mm rear adjuster is selected over a fixed-stroke SAI when you need variable end-stops for product changeovers. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for positive locking, consider the SAIL or BSAI series. With a 190mm stroke, the 25mm rod handles moderate side loads, but an external guide is recommended for heavy off-center loads.
To match this ISO 15552 interchangeable cylinder, confirm an 80mm bore, 190mm nominal stroke, 30mm adjustment range, PT G3/8 ports, and your required mounting style. This SKU does not include a magnet for sensor tracking.
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 SAIJ80AX190-30 FAQ
At 0.5 MPa, the push force is 2513N.
The rear adjusting screw acts as a mechanical stop that lets you trim the effective stroke back by up to 30mm, creating a 160 to 190mm usable travel window. It sets the end position but does not lock the load without continuous air pressure.
