About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-20S
The AirTAC SAIJ80X115-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet supports position sensing via AirTAC CMSE reed and DMSE electronic switches housed in the dual-side sensor grooves.
With a 115mm nominal stroke and a 20mm adjustment range, this model provides a precise 95-115mm usable travel window. This built-in rear stopper allows you to fine-tune the end position during commissioning without adding external stops. It utilizes PT tapered ports and adjustable air cushions at both ends to manage deceleration.

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 SAIJ80BX115-20S Is Used
Machine Changeover
Dial in the 95-115mm travel window during product size changes without swapping out the entire cylinder or re-engineering fixed external stops.
End-Position Tuning
Fine-tune the retract end-point at commissioning to perfect a 2513N press or clamping motion, absorbing mechanical tolerance variations.
Variable Stops
Adjust the stroke on the fly for sorting or diverting operations on a conveyor line where package sizes frequently vary.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-20S the Right Cylinder?
The adjustable 95-115mm travel window is ideal for product changeovers, whereas a fixed-stroke SAI cylinder suits static end positions. Remember that the rear adjuster acts only as a travel stop, not a load lock; for position holding without live air, select an AirTAC SAIL or BSAI cylinder. To replace this cylinder, match the 80mm bore, 115mm stroke, 20mm adjuster, PT ports, and -S magnet.
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 SAIJ80BX115-20S FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the 115mm nominal stroke by up to 20mm, creating a 95-115mm usable travel window. It sets the end position but does not lock the load without live air pressure.
