About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-100S
The AirTAC SAIJ80X165-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits you to trim the nominal 165 mm travel back by up to 100 mm. This yields a highly flexible 65-165 mm usable stroke window, allowing precise end-position tuning during commissioning without swapping out the physical barrel or adding external mechanical stops.
Equipped with a SUS304 stainless steel rod (option B) and a -S magnet, this unit supports AirTAC CMSE reed and DMSE solid-state sensors via the dual-side extruded barrel grooves. The 25 mm rod and M20x1.5 thread provide high rigidity, while the rear adjuster acts strictly as a travel stop for deceleration setup, not as a load-holding lock.

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 SAIJ80BX165-100S Is Used
Variable End-Stop Tuning
Dial in the exact extension point within the 65-165 mm window during machine commissioning to accommodate varying material thicknesses without disassembling the pneumatic line.
Product Size Changeover
Rapidly adjust the stroke length on packaging lines processing different carton dimensions, using the rear screw to set new end positions in seconds.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-100S the Right Cylinder?
The 100 mm adjustment range here is particularly valuable for machines handling multiple product sizes, as the rear screw allows rapid changeover without hardware modification.
This SAIJ80X165-100-S model features PT tapered port threads (G3/8) and uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Because it is a plain adjustable cylinder, the rear stopper and air cushions cannot hold a load without live air; for fail-safe load holding, consider the SAIL or BSAI series. Although the 165 mm stroke is moderate, always ensure external guides support the load to prevent excessive side-loading on the rod.
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 SAIJ80BX165-100S FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 100 mm from the nominal 165 mm stroke, providing a usable 65-165 mm window. It acts as a mechanical stop to set the end position and must not be relied upon to hold a load without continuous air pressure.
The -S option includes a magnet for position sensing, compatible with AirTAC CMSE reed switches and DMSE solid-state sensors mounted in the barrel grooves.
