About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-20
The AirTAC SAIJ80X220-20 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 220 mm stroke that can be fine-tuned down by up to 20 mm, giving you a precise 200-220 mm usable travel window during commissioning.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster acts strictly as a travel stop for deceleration and positioning, not as a locking device to hold the load without continuous air pressure.

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 SAIJ80BX220-20 Is Used
Product Changeovers
Dial in the 200-220 mm stroke window instantly on the rear screw when switching between slightly different product sizes on the line.
Machine Setup
Fine-tune the end-of-stroke position during initial commissioning without fabricating or bolting on custom external stoppers.
Variable End Stops
Adjust the retraction point on the fly for diverter gates or pushing mechanisms that handle varying package depths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-20 the Right Cylinder?
The adjustable 200-220 mm window is ideal for product changeovers, allowing you to dial in the exact stroke on the machine floor instead of swapping out a fixed-length SAI cylinder. When ordering an ISO 15552 replacement, match the 80 mm bore, 220 mm stroke, 20 mm adjustment, PT G3/8 port, and your required mounting hardware. Since the 220 mm stroke exceeds 300 mm? No, but for any future longer strokes, always ensure external guiding to prevent side-loading damage. For applications requiring true load-holding without live air pressure, consider the SAIL or BSAI series instead of relying on this adjuster.
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 SAIJ80BX220-20 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw lets you shorten the effective travel from the 220 mm nominal stroke down to 200 mm. It acts as a mechanical stop to set the exact end position, but it does not lock the load without continuous air pressure.
