About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-40
The AirTAC SAIJ80X190-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 190 mm travel back by up to 40 mm, creating a precise 150-190 mm usable window. This on-board stopper lets you fine-tune the retract end position at commissioning or during product changeovers without swapping out the physical actuator.
This variant is configured with an SUS420J2 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for straightforward positioning feedback. The rear adjuster acts purely as a travel stop to set the end position and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

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 SAIJ80AX190-40 Is Used
Changeover Adjustment
Dial in the 150-190 mm travel window during product size changeovers on a packaging line without replacing the cylinder or repositioning hard stops.
End-Position Tuning
Fine-tune the retract end position during machine commissioning to perfect the pressing or clamping depth on varying material thicknesses.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-40 the Right Cylinder?
Choose this 80 mm bore actuator when an application demands high thrust—2513 N at 0.5 MPa or 3518 N at 0.7 MPa—and requires variable end-stop positioning within a 150-190 mm travel window. If your force requirements are lower, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa, whereas stepping up to a 100 mm bore provides 3927 N at 0.5 MPa. The adjustable rear screw is ideal for machine setups where you need to dial in the exact retract distance on the fly rather than machining external stops or ordering a custom fixed-stroke SAI cylinder.
When integrating this model, note that the 25 mm rod and M20x1.5 thread provide excellent rigidity, but any stroke of 190 mm still requires an external guide to prevent side-loading damage. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). To achieve a true ISO 15552 replacement match, verify the 80 mm bore, 190 mm stroke, 40 mm adjustment, G3/8 PT port, and specific mounting accessories.

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 SAIJ80AX190-40 FAQ
An external adjusting screw at the rear acts as a mechanical stop, allowing you to shorten the effective stroke by up to 40 mm. This creates a usable travel window of 150-190 mm, letting you fine-tune the end position without adding external stops.
At 0.7 MPa, the push force increases to 3518 N.
