About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-30S
The AirTAC SAIJ80X195-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you dial back the travel by up to 30 mm. This creates a usable 165-195 mm end-position window, allowing precise fine-tuning during commissioning or product changeovers without swapping the barrel or adding external stops.
This unit includes a magnet for CMSE reed and DMSE electronic sensors, fitting into the dual-side sensor grooves of the extruded aluminum barrel. It uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. The rear adjuster acts purely as a travel stop to set deceleration limits 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 SAIJ80BX195-30S Is Used
Machine Changeover
Dial in the 165-195 mm travel window during product size transitions to set new end-stops rapidly without changing the cylinder.
End-Position Tuning
Fine-tune the exact retract position during commissioning using the rear screw, avoiding the need for external mechanical stops.
Variable Assembly Stops
Adjust the stroke on the fly for multi-model assembly lines that require different retract distances from the same fixture.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-30S the Right Cylinder?
The adjustable 165-195 mm travel window is ideal for machinery requiring variable end-stops, offering more setup flexibility than a fixed-stroke SAI cylinder. Because the stroke is under 300 mm, side-load risks are moderate, but the 25 mm rod and M20x1.5 thread still handle lateral forces better than smaller bores.
For load-holding without continuous air pressure, note that the rear adjuster is only a stop, not a lock; you would need an external pilot-operated check valve or a related SAIL pneumatic lock cylinder. To replace this unit on an ISO 15552 line, match the 80 mm bore, 195 mm stroke, 30 mm adjustment, PT port, and the -S magnet requirement.
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 SAIJ80BX195-30S FAQ
The rear adjuster screw allows you to shorten the nominal 195 mm stroke by up to 30 mm, providing a usable travel window of 165-195 mm. It functions as a mechanical stop to set the end position and does not lock the load without live air pressure.
