About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-100
The AirTAC SAIJ80X180-100 is a double-acting ISO 15552 profile cylinder featuring a substantial 100 mm rear stroke adjustment range. This creates a versatile 80-180 mm usable travel window, allowing you to dial back the nominal 180 mm stroke for exact end-position tuning during commissioning.
This configuration omits the -S magnet option, meaning it operates without position sensing out of the box. The barrel is extruded aluminum with sensor grooves on both sides should you later add switches. It uses PT tapered ports sized at G3/8 and relies on a 36 mm air cushion at both ends to decelerate the load smoothly.

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 SAIJ80BX180-100 Is Used
Machine Changeover
Rapidly reconfigure the 80-180 mm travel window during product size transitions on a packaging line without replacing the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the final retract position during machine commissioning to achieve exact mechanical alignment, absorbing minor fabrication tolerances.
Variable End Stops
Create a flexible testing rig where the stroke limit can be dialed back by up to 100 mm to test component fatigue at different travel lengths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-100 the Right Cylinder?
The 100 mm adjustment range is ideal for product-size changeovers on a line, letting operators set a new end-stop without swapping the cylinder or adding external stops. Remember that the rear adjuster is a travel stop, not a lock; this SAIJ will not hold its load without live air pressure. For true fail-safe load holding, select an AirTAC SAIL or BSAI cylinder instead.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 180 mm nominal stroke, 100 mm adjustment code, G3/8 PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2—omitting FB, CA, CB, CR). The SUS304 stainless steel rod (code B) provides excellent corrosion resistance for wet or washdown environments.
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 SAIJ80BX180-100 FAQ
An external adjusting screw at the rear acts as a stopper, allowing you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 80-180 mm from the nominal 180 mm stroke, which is set mechanically at commissioning without live air.
