About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-20
The AirTAC SAIJ80X220-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 20 mm, creating a precise 200-220 mm usable stroke window.
This model features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, while the adjustable rear stopper acts purely as a travel end-limit and does not hold the load without live air pressure.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80AX220-20 Is Used
Product Changeovers
Dial in the 200-220 mm travel window during format changes to accommodate varying package dimensions without swapping hardware.
Machine Setup
Fine-tune the retract end-position at commissioning to perfect alignment, avoiding the need for external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-20 the Right Cylinder?
Choose this 80 mm bore cylinder when an application requires substantial thrust combined with on-the-fly end-position tuning during commissioning or product changeovers. Because the nominal stroke is 220 mm, an external guide is recommended to manage side loads on the rod.
The SAIJ80X220-20 is dimensionally interchangeable with ISO 15552 cylinders and supports a mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster functions only as a stop, not a lock; for load-holding without live air pressure, consider the AirTAC SAIL or BSAI 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 SAIJ80AX220-20 FAQ
The rear adjuster screw lets you shorten the nominal 220 mm stroke by up to 20 mm, providing a usable travel window of 200-220 mm for fine-tuning the end position without replacing the cylinder.
