About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX210-100
The AirTAC SAIJ80X210-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 110 to 210 mm, enabling precise end-position tuning at commissioning without external stops.
This model features a SUS420J2 stainless steel rod for corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live 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 SAIJ80AX210-100 Is Used
Machine Changeover
Dial in the 110-210 mm travel window during product size transitions to set new end positions rapidly without changing the cylinder.
End-Position Tuning
Fine-tune the retract stroke at commissioning using the rear stopper to perfect timing without adding external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX210-100 the Right Cylinder?
Choose this adjustable-stroke model when an application requires variable end-stops or frequent product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. If your setup requires less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa. Because the 210 mm stroke exceeds 300 mm is false here, a side-load guide is less critical, but the 25 mm rod diameter handles standard bending stresses well.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 210 mm stroke, 100 mm adjustment, PT port threads, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interfaces. Note that SAIJ omits the FB, CA, CB, and CR mounts. For load-holding without live air pressure, consider the SAIL or BSAI series instead.
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 SAIJ80AX210-100 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The nominal stroke is 210 mm, and the 100 mm adjustment code allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 110 to 210 mm.
