About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-30S
The AirTAC SAIJ80X220-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 25mm piston rod and a 220mm nominal stroke that can be fine-tuned down by up to 30mm, yielding a usable travel window of 190-220mm. This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for electronic position sensing.
Because it is an extruded aluminum profile cylinder rather than a tie-rod type, it integrates standardized ISO 15552 mounting dimensions seamlessly. The rear adjuster functions strictly as a mechanical stop to dial in the exact retract end-position during commissioning. It does not lock or hold the load without live air pressure; for fail-safe load holding, you would need a SAIL or BSAI variant. The barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE solid-state switches.

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 SAIJ80BX220-30S Is Used
Product Changeover
Dial in the 190-220mm retract position on the fly when switching between product sizes on a packaging line, avoiding mechanical teardown.
End-Position Tuning
Use the 30mm rear stopper screw to perfectly align tooling picks at commissioning without adding external physical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-30S the Right Cylinder?
The 30mm adjustment range is perfect for applications requiring precise variable end-stops during product changeovers, eliminating the need to physically swap out a fixed-stroke SAI cylinder. Since the 220mm stroke exceeds 300mm? No, but even at 220mm, if you experience high side-loading, an external guide should support the load to prevent premature rod wear.
When matching this ISO 15552 cylinder for a replacement, verify the 80mm bore, 220mm stroke, 30mm adjustment, PT tapered port threads, and the -S magnet option. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. The operating speed ranges from 30 to 800 mm/s.

- ✓ 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 SAIJ80BX220-30S FAQ
The maximum thrust at 1.0 MPa is 513 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 220mm nominal stroke by up to 30mm, providing a usable travel window of 190-220mm. It only sets the travel end and does not hold the load without continuous air pressure.
