About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-75
By turning the rear stopper screw, you can trim the nominal 220mm stroke back by up to 75mm, creating a precise 145-220mm usable travel window for exact end-position tuning during commissioning. This cylinder features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads.
Because this is an 80mm bore unit with a 220mm stroke, the robust 25mm rod and M20x1.5 rod thread provide excellent resistance to bending under moderate side loads, though long unsupported travel still requires external guiding. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount CMSE reed or DMSE electronic switches if position feedback is later required.

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 SAIJ80BX220-75 Is Used
Machine Changeover
Dial in the 145-220mm travel window during product size changes to set new retract endpoints without physically replacing the cylinder.
End-Position Trimming
Fine-tune the final retract position at commissioning using the 75mm rear stopper screw to perfect tooling alignment.
Variable Stops Assembly
Ideal for assembly stations needing flexible end-of-stroke positioning across multiple fixture lengths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-75 the Right Cylinder?
If you need less force, stepping down to a 63mm bore yields 1559N; if you require significantly more push capacity, a 100mm bore provides 3927N. The SAIJ80X220-75 is chosen over a fixed-stroke SAI model when product changeovers demand a adjustable retract endpoint without swapping out the entire actuator or adding external mechanical stops.
For an exact ISO 15552 dimensional replacement, match the 80mm bore, 220mm nominal stroke, 75mm adjustment range, PT port threads, SUS304 (B) rod material, and the standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock or the SAIL/BSAI locking 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 SAIJ80BX220-75 FAQ
It features a rear stopper screw that allows you to shorten the effective stroke by up to 75mm. This creates a usable travel window of 145-220mm, letting you fine-tune the retract end position without changing the cylinder.
