About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-40S
By turning the rear stopper screw, you can trim the effective travel back by up to 40 mm, creating a precise 125-165 mm usable window. This allows you to dial in the exact retract end-position during commissioning without swapping out the entire cylinder or adding bulky external stops.
This SKU is built with an SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and features a -S magnet for position sensing. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept AirTAC CMSE reed or DMSE electronic solid-state switches. It uses a G3/8 port and relies on variable air cushions 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 SAIJ80AX165-40S Is Used
Product Changeover
Quickly fine-tune the 125-165 mm retract distance on packaging lines when switching to different carton sizes, avoiding mechanical rebuilds.
End-Position Tuning
Dial in the exact stopping point during machine commissioning to prevent over-travel and crush damage on delicate workpieces.
Variable Diverter Stops
Adjust the stroke on the fly to handle varying pallet dimensions on a conveyor line without repositioning the cylinder mount.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-40S the Right Cylinder?
The adjustable 125-165 mm travel window is perfect for machines that require variable end-stops or frequent product-size changeovers, saving the downtime of physically replacing a fixed-stroke SAI cylinder.
When ordering an ISO 15552 replacement, match the 80 mm bore, 165 mm nominal stroke, 40 mm adjustment range, PT tapered port thread, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Remember that the rear adjuster is a travel stop, not a lock; the cylinder cannot hold a load without live air, so specify a SAIL or BSAI model if fail-safe load holding is required.
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 SAIJ80AX165-40S FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 165 mm nominal stroke by up to 40 mm. This creates a usable travel window of 125-165 mm for precise end-position tuning.
