About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-100S
The AirTAC SAIJ80X190-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 190 mm nominal stroke that can be dialed back by up to 100 mm, creating a wide 90-190 mm usable travel window for highly flexible end-position tuning.
This adjustable model uses an external stopper screw at the retract end to fine-tune travel without swapping the cylinder or adding external stops. The adjuster acts only as a travel stop and does not hold the load without live air pressure. Mounting options include the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ80BX190-100S Is Used
Product Changeover
Dial the stroke back from 190 mm to 90 mm during line changeovers to accommodate different product lengths without replacing the actuator.
End-Position Tuning
Fine-tune the exact retract position during machine commissioning using the rear stopper, avoiding the need to add external mechanical shims.
Variable End Stops
Set precise travel windows for multi-stage assembly processes where the cylinder must contact the adjustable stop at different points in the cycle.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-100S the Right Cylinder?
If your application needs less force, stepping down to a 63 mm bore yields 2182 N at 0.7 MPa. Conversely, a 100 mm bore provides 5497 N at 0.7 MPa for heavier loads. The adjustable stroke is ideal for commissioning fine-tunes where a fixed-stroke SAI cylinder would require shimming or mechanical rework. Because the nominal stroke is 190 mm, an external guide is recommended for optimal side-load management. For load-holding without live air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is not a lock. This configuration includes a -S magnet for CMSE reed and DMSE electronic sensors.

- ✓ 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 SAIJ80BX190-100S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 100 mm. This provides a usable travel window between 90 and 190 mm, allowing you to trim the retract end-position without changing the cylinder.
It operates at speeds between 30 and 800 mm/s.
