About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX210-40S
The AirTAC SAIJ80X210-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 170 to 210 mm, allowing you to dial back the nominal 210 mm stroke by up to 40 mm during commissioning. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection integration.
Equipped with a -S magnet and SUS420J2 stainless steel rod (option A), this unit supports AirTAC CMSE reed and DMSE electronic sensors. The G3/8 PT tapered ports and 36 mm cushions handle the 30-800 mm/s speed range. The rear adjuster functions strictly as a travel stop for end-position tuning, not a load lock, so live air pressure must be maintained to hold a load.

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 SAIJ80AX210-40S Is Used
Machine Changeover
Quickly fine-tune the 170-210 mm travel window during product size transitions on a packaging line without replacing the physical cylinder.
End-Stop Calibration
Dial in the exact retract position during initial commissioning, using the rear stopper to compensate for mechanical tolerance stack-up.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX210-40S the Right Cylinder?
Select this 80 mm bore model when an application requires substantial thrust—stepping down to a 63 mm cylinder drops the 0.5 MPa push force to 1559 N, whereas moving up to a 100 mm bore increases it to 3927 N. The 40 mm adjustable range is ideal for product changeovers, letting operators set variable end-stops without physically swapping the cylinder or adding external stops. For load-holding without continuous air pressure, this cylinder is insufficient; consider an AirTAC SAIL, BSAI clamp-lock, or an external pilot-operated check valve.
Because the 210 mm stroke exceeds 300 mm only in larger configurations, this specific travel length is relatively compact, but the 25 mm rod and M20x1.5 thread still require external guidance if subjected to heavy lateral loads. This SAIJ variant uses the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable with ISO 15552 cylinders.
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 SAIJ80AX210-40S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 40 mm. This creates a usable travel window of 170 to 210 mm, allowing precise end-position tuning without changing the cylinder itself.
At the maximum 1.0 MPa pressure, the push force reaches 4523 N.
