About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-100S
The AirTAC SAIJ80X195-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 95-195 mm. The extruded aluminum barrel includes sensor grooves on both sides, and this variant features a SUS304 stainless steel rod for superior corrosion resistance.
Because the rear screw acts purely as a mechanical stop, it allows precise end-position tuning during commissioning or product changeover without adding external stops. However, this adjuster is not a lock; the cylinder cannot hold a load without live air pressure. For position-holding requirements, consider the SAIL or BSAI series instead.

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 SAIJ80BX195-100S Is Used
Variable End-Stop Positioning
Dial in the retract position within the 95-195 mm window during machine setup to accommodate different product lengths without changing hardware.
Corrosive Environment Actuation
Utilize the SUS304 stainless steel rod in washdown or chemically exposed areas where standard carbon steel rods would degrade.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-100S the Right Cylinder?
The 100 mm adjustment range is particularly valuable for machines processing variable product sizes, allowing you to fine-tune the retract end on the fly rather than swapping out a fixed-stroke SAI cylinder.
This configuration uses a PT tapered port and includes a magnet for CMSE and DMSE sensors. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the stroke is under 300 mm, side-load concerns are minimal, but an external guide is still recommended for heavy lateral loads. Note that the air cushions and rear stopper do not function as a brake.
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 SAIJ80BX195-100S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 195 mm down to 95 mm. This allows precise end-position tuning during commissioning without swapping the cylinder, though it does not lock the load without live air.
