About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-40S
The AirTAC SAIJ80X195-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 25mm SUS304 stainless steel piston rod and PT tapered G3/8 ports. By turning the external rear screw, you can shorten the effective travel, providing a usable stroke window of 155 to 195 mm for precise end-position tuning during commissioning.
The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes the -S magnet, it is fully compatible with AirTAC CMSE reed and DMSE solid-state switches for exact position feedback. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

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 SAIJ80BX195-40S Is Used
Machine Changeover
Dial in the retract end-position from 195 mm down to 155 mm during product size changes without swapping the cylinder or reworking the fixture.
End-Stop Tuning
Fine-tune the final resting position during initial commissioning to absorb mechanical tolerance and guarantee precise placement of the 25mm SUS304 rod.
Variable Diverters
Adjust the stroke length on the fly for pneumatic diverters or gates that must reposition to handle different package sizes on a single line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-40S the Right Cylinder?
The adjustable rear stopper is ideal for product changeovers, allowing you to shift the travel window from 195 mm down to 155 mm on the fly.
To replace an ISO 15552 cylinder, match the 80mm bore, 195mm stroke, 40mm adjustment range, PT G3/8 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR mounts. For applications needing the cylinder to hold a load without live air, the rear stopper is insufficient; consider the SAIL air-released lock or BSAI clamp-lock series instead.
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 SAIJ80BX195-40S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 513 kgf of push force.
The rear external adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 195 mm down to a minimum of 155 mm. This creates a 40 mm adjustable window for fine-tuning the end position without replacing the cylinder.
